Current Challenges in the Physics of White Dwarf Stars

Meeting Dates: 2024 Mar 25 - 29
Meeting Location: Santa Fe, NM, USA

This conference brings together the communities of white dwarf modelers and dense matter physicists to foster new collaborations and identify astrophysical problems that can be addressed with advanced physical theories, simulations, and experiments.

SCIENTIFIC MOTIVATION

White dwarf stars represent the end stage of the life of the vast majority of stars, including our Sun. These common stars are the sites of exotic physical conditions that are not encountered in other stars. Matter in such extreme conditions is beginning to be probed experimentally. Historically, theoretical work in dense plasma physics has found fertile applications in white dwarf models. The astrophysics of white dwarfs is a mature field, yet modern observations challenge many aspects of the models in regimes ranging from the relatively low-density gas at the observable surface through the deeper regions of partial ionization to the dense core. In many instances, modern physical theories, simulation methods and experimental techniques can be fruitfully applied to drive the field to a new level of understanding and resolve outstanding astrophysical problems.

Topics to be covered include:

  • Astrophysics of white dwarf stars
  • Physical processes in white dwarf stars
  • Radiative opacities in dense gases and plasmas
  • Equation of state and transport coefficients
  • Magnetic fields
  • Crystallization and phase diagrams
  • Models and simulations of warm dense plasmas
  • Experimental measurements
WORKSHOP FORMAT

The workshop is intended to foster exchanges between different communities with the goal of identifying problems ripe for investigation. The program will consist of a limited number of invited overview talks on key topics in white dwarf astrophysics, matched with presentations of the relevant current physics methods. Scheduled group discussions will explore selected topics in greater details. Contributed posters will be up during the entire workshop and there will be ample time for discussions. We encourage the participation of young researchers. A limited number of travel grants will be available to assist students and postdocs.

WORKSHOP ORGANIZERS

Didier Saumon (Los Alamos National Laboratory, USA, co-chair); Jerome Daligault (Los Alamos National Laboratory, USA, co-chair); Simon Blouin (U. Victoria, Canada); Stephanie Hansen (Sandia National Laboratories, USA); Amy Lazicki (Lawrence Livermore National Laboratory, USA); Nicole Reindl (Zentrum für Astronomie der Universität Heidelberg, Germany)

Recipes to Regulate Star Formation at All Scales: From the Nearby Universe to the First Galaxies

Meeting Dates: 2024 Apr 15 - 19
Meeting Location: Baltimore, MD, USA
Abstract Deadline: 2024 Jan 19
Registration Deadline: 2024 Mar 15

Star formation is a fundamental process defining galaxies, impacting virtually every facet of astronomy. However, precise mechanisms governing star formation activity, including but not limited to stellar and AGN feedback, and its evolution with redshift remain a subject of intense debate. With recent observations from cutting-edge (ground-based and space telescopes) observatories (e.g., JWST, HST, ALMA, VLT, Keck) unprecedented data have become available to study star formation at all redshifts. While state-of-the-art simulations are aiding us in the construction of increasingly more realistic models of galaxy formation and evolution to predict and interpret these observables, high redshift observations cannot provide the level of cloud-scale physical detail that the nearby galaxies have to offer. The 2024 STScl Spring Symposium aims to gather the low, intermediate and high-redshift communities to discuss the factors that affect star formation in galaxies, from parsec to kiloparsec and megaparsec scales. We will highlight new observational, theoretical and computational results from the nearby Universe to Cosmic Noon (z~2-3) and up to the first galaxies in the Epoch of Reionization (z>6) on the following four core topics:

  1. Conditions for star formation in galaxies and the role of stellar feedback;
  2. The relationship between star formation and chemical evolution;
  3. The role of AGN feedback in regulating star formation;
  4. The CGM and IGM role in shaping star formation activity in galaxies.
The synergy between new observations of nearby systems and theoretical studies will shed light on the interpretation of the results from more distant galaxies. Furthermore, the results from distant galaxies will in turn give us insights on the best way to identify local analogs to better understand the star formation processes in earlier times. This will also prepare the field for forthcoming observatories (e.g., Euclid, Vera Rubin Observatory, Roman, ELTs, SKA). This Symposium aims to enhance our understanding of the drivers of galaxy evolution, a key topic highlighted amongst the Astro 2020 priority areas. Here, we list the open questions we will explore and discuss:

Conditions for star formation in galaxies and the role of stellar feedback

  • What are the best star formation rate indicators at different physical scales and epochs? How does the presence of dust affect them across cosmic time?
  • What drives the star formation activity in galaxies, from cloud-scales to galactic scales?
  • How does stellar feedback affect the gas supply for star formation in galaxies across cosmic time?
The relationship between star formation and chemical evolution

  • What are the most effective ways to trace both stellar and gas-phase metallicities at different epochs?
  • How does star formation enrich the galaxy with metals from the early to the nearby Universe?
  • What is the interplay between metal distribution and star-formation, and does it change across cosmic time?
The role of AGN feedback in regulating star formation

  • How do we detect AGN at different epochs?
  • What is the impact of AGN feedback on star formation across cosmic time?
  • How do the Black hole-galaxy scaling relations (MBH-σ, MBH-M*) vary with redshift?
The CGM and IGM role in shaping star formation activity in galaxies

  • How can kiloparsec or megaparsec-scale variations in the environment affect star-formation on micro-scales?
  • What can we learn about the baryon cycle in galaxies (SF-AGN interplay, inflows & outflows, metal dilution/enrichment) via observations of the CGM and IGM at different epochs?

Anticipating the Rising Tide of Tidal Disruption Events: Theory and Observations

Meeting Dates: 2024 Apr 23 - 26
Meeting Location: Santa Barbara, CA, USA
Absract Deadline: 2024 Mar 1
Registration Deadline: 2024 Mar 24

Tidal disruption events (TDEs), which occur when a star is destroyed by the immense tidal field of a supermassive black hole, fuel luminous accretion flares that provide unique insight into the properties of galactic nuclei and their central black holes. The detection rate of these events has accelerated in recent years thanks to advances in wide-field survey capabilities across the electromagnetic spectrum. Nonetheless, there remain theoretical uncertainties in the modeling of TDEs that obfuscate understanding in the face of observations, and our ability to use TDEs as a collective Rosetta Stone for deciphering black hole demographics across cosmic time remains elusive. To bridge theory and observation and to start to tap the wealth of understanding contained within TDE observations, this conference aims to unite the diverse field of astronomers working on TDEs and the related fields of variable Active Galactic Nuclei (AGN) and X-ray binaries. This conference will highlight the recent advances that have been made in understanding TDEs, make connections to related astrophysical phenomena, and elucidate the most outstanding questions in TDE theory and observation.

For this conference, upon registering you will have the opportunity to submit an abstract to present your work, the deadline for abstract submission is March 1st. We have a limited number of remaining slots to be filled with contributed talks, and in the event that we are unable to fit you into the talk schedule, we may be able to assign your abstract to a poster that will be displayed throughout the duration of the conference. Each poster board is 4 feet high x 6 feet wide. We ask that the posters be no larger than 44 inches high x 34 inches wide at the most (it is important to follow these measurements or posters may be turned down due to limited space).

For additional questions, please see the conference website.

"Some like it hot!" A Journey from the Hot IGRM to the Multiphase CGM

Meeting Dates: 2024 April 22 - May 17
Meeting Location: MIAPbP, Munich, Germany
Registration Deadline: 2023 Sep 24

The exchange of mass, energy, and metals between galaxies, their surrounding circum-galactic medium (CGM), and the gas permeating halos at larger scale represents a fundamental part of the modern astrophysics. Both components still elude our knowledge. Indeed, we are very far from having a census of the CGM properties in the bulk of the galaxy population. Furthermore, the halo gas is well known at large scale only in the most massive halos of our Universe, the galaxy clusters (intra-cluster medium, ICM), but it is still very elusive in the bulk of the virtualized halo population at the group mass scale (Intra-group medium IGrM).

For this reason, so far, the study of such baryon cycle has been linked almost exclusively to galaxy evolution in a so called "streetlight bias". Albeit more difficult to detect, the IGrM and the CGM are the other two key players on the stage, and their evolution across cosmic time is linked to the baryon exchange as much as the galactic component. Due to the substantial lack of information on the nature of the CGM and IGrM at large scales, many key questions remain unanswered. For instance, how is the IGrM affected at large scales by the feedback imparted energy? In other words, how does the baryon cycle affect the large-scale structure of our Universe? How much energy, momentum and entropy are released to the still elusive CGM hot component around galaxies? What is the main mechanism of interplay between CGM and central galaxy?

With the advent of instrument such as eROSITA, XRISM and JWST, and the enormous variety of results collected by Alma, MUSE, KCWI and LOFAR, it is time to review the state of the art of this research field. The final goal of this workshop is to fill the knowledge gap and review in an unbiased way all the key aspects of the baryon cycle: from the hot IGrM enclosed in the bulk of the virtualized halo population, to the CGM at hundreds of kpc from the central galaxy, and down to the main mechanisms in act at the galaxy center able to trigger the baryonic exchange.

Towards a Physical Understanding of Tidal Disruption Events

Meeting Dates: 2024 Apr 22 - 25
Meeting Location: Santa Barbara, CA, USA
Application Deadline: 2023 Jan 29

A tidal disruption event (TDE) occurs when a star is pulled apart by the gravitational field of a supermassive black hole (SMBH), transforming the star into a stream of stellar debris. In a matter of months, a fraction of this debris stream returns to the SMBH and ignites an accretion flare in the nucleus of the galaxy where it resides. TDEs have been observed in great detail across the electromagnetic spectrum; from the initial rise in flux to the decay back to quiescence. Such observations may enable an inference of the SMBH and disrupted star properties, while also providing a unique window into poorly understood aspects of accretion theory, such as the nature of super-Eddington flows and the production of jets and outflows. The large increase in observational data for TDEs will provide an unprecedented census of the low-mass end of the SMBH population, but to take full advantage of this influx of data, we need robust and predictive theoretical models for the radiation from these events. The goal of this program is to bring theorists and observers together to answer some of the most pressing questions on the physics of TDEs. From the processes that generate stars on fateful orbits toward the SMBH, to the initial destruction of the star and the formation of an accretion flow, to the production of high-energy radiation and outflows, this program aims to test, revise and extend our current understanding of TDEs.

Science with the Hubble and James Webb Space Telescopes VII: Stars, Gas & Dust in the Universe

Meeting Dates: 2024 Apr 29 - May 2
Meeting Location: Porto, Portugal
Abstract submission deadline: 2024 Jan 26
Registration deadline: 2024 Mar 22

We are delighted to announce the latest in a series of ESA-sponsored conferences, in collaboration with STScI, which highlight the scientific impact of the Hubble and James Webb Space Telescopes. After much anticipation of their complementary capabilities, we are now in the remarkable period of having these two pioneering observatories in science operations at the same time — the much-heralded Golden Age for UV-optical-IR space astronomy has arrived!

Hubble, a long-standing partnership between NASA and ESA, is continuing to surprise and inspire us with new results and breakthroughs. As we look ahead to the 35th year of science operations, its use and powerful complementarity with other facilities continues to evolve, with the community finding novel and innovative applications for its unmatched ultraviolet-visible capabilities.

We are now also witnessing the first exciting results from JWST, a collaboration between NASA, ESA, and the CSA. With performance beyond our expectations, JWST is quickly transforming our view of the universe on all scales, from new insights in our Solar system and nearby exoplanets, to revealing the formation and growth of the very first galaxies and black holes.

These two observatories are now combining to give us unique views of stars, gas and dust in the universe. These span the processes of nearby star and planet formation, the properties of the interstellar medium in galaxies near and far, the production of dust in supernovae and evolved stars, and new insights into the dust content and star formation in the early Universe.

Of course, Hubble and Webb are far from working alone. A broad range of ground-based and space-borne facilities are helping to provide us with a multi-wavelength view to unlock our understanding of the Universe. These include the rich legacy from the Gaia mission, the start of science operations with Euclid to explore the dark Universe, the exquisite resolution and sensitivity of ALMA in the sub-mm, and the imminent first light of the Rubin Observatory. Looking ahead, the second half of the decade will bring major new space missions, such as Roman, PLATO and ARIEL, and the first light of the European Extremely Large Telescope.

The science program will feature a combination of invited and contributed talks, with the objectives to:

  • Highlight the latest Hubble and Webb results in studies of stars, gas and dust over all scales, with a focus on results with strong synergies between the two missions and with other facilities.
  • Identify key topics for new programs and initiatives that will harness the powerful combined capabilities of these two observatories.
  • Explore future synergies of Hubble and Webb with other existing and planned facilities.
  • Look ahead to the future scientific questions that will shape astrophysics into the 2030s and beyond.

Extreme Galaxies in their Extreme Environments at Extremely Early Epochs

Meeting Dates: 2024 Apr 29 - May 3
Meeting Location: Reykjavik, Iceland
Abstract Deadline: 2023 Nov 15
Early Registration Deadline: 2024 Jan 31
Early Registration Deadline: 2024 May 1

Extreme galaxies and extreme environments have long served as key benchmarks for models of galaxy formation. The mere existence of such galaxies and environments creates significant challenges to physical models of galaxy formation, as such models must be able to explain the formation of "normal galaxies" in "normal environments" as well as the extreme tail of the galaxy and environmental distribution. For example, massive and quenched/strongly star-forming galaxies have long placed significant constraints on quenching models. Likewise, the existence of proto-clusters containing both strongly starbursting and quenched galaxies are forcing us to reevaluate the effect of environment on galaxy evolution at high redshift. Studies at 1 < z < 2 have raised a host of new questions about galaxy evolution that can only be answered by turning our gaze to even higher redshift. Fortuitously, the coming of observatories such as JWST, ALMA and the upcoming Euclid and Roman Missions are opening up the study of the z > 2 universe with large surveys that make possible the study of extreme galaxies and extreme environments at the very highest redshifts. The goal of this meeting is to bring together theoreticians and observational astronomers working on extreme galaxies in extreme environments at z > 2 to summarize the state of these fields and discuss how they are pushing forward our understanding of the physics of galaxy formation.

This 5-day meeting will focus on 4 key themes under the general topic of extreme objects. The four topics that will be discussed in the meeting are:

  1. Extreme galaxies: Massive galaxies, dusty-star-forming galaxies, high/low mass quiescent galaxies, AGN, and other extreme objects
  2. Extreme environments: Proto-clusters, galaxy overdensities, and voids
  3. Extreme galaxies in extreme environments: Is the evolution of extreme galaxies and environment linked at high-redshift and if so, how?
  4. The evolution with time of extreme galaxies and environments: How do these extreme environments/objects connect to lower-redshift descendants (z < 2) and what does this tell us about the physics of galaxy formation?
The "extreme" landscape and environment of Iceland should provide the ideal backdrop for lively discussion and debate! We envisage an engaging and lively meeting in which we discuss the status, challenges and prospects for these specific areas of galaxy evolution. We also envisage intense discussion/brainstorming sessions to summarize where we are, what we do not understand, what is controversial and how we can make progress in the next few years. This is meant to be a mid-sized conference with ~100-120 participants. Organizers:

Benedetta Vulcani, INAF OaPD (chair); Adam Muzzin, York University (co-chair); Greg Rudnick, University of Kansas (co-chair) Scientific organizing committee (SOC):

Gabriella De Lucia; Michele Fumagalli; Nina Hatch; Jackie Hodge; Adam Muzzin; Greg Rudnick; Rhea-Silvia Remus; Sandro Tacchella; Benedetta Vulcani; Kate Whitaker

Gravitational waves: a new ear on the chemistry of galaxies

Meeting Dates: 2024 April 29 - May 3
Meeting Location: Leiden, The Netherlands

The fields of gravitational-wave astrophysics and galaxy evolution have a vast amount to learn from one another. Understanding the evolution and chemical enrichment of galaxies is crucial to unravelling the evolutionary origin of black hole/neutron star mergers, which are now regularly detected via gravitational waves. Correspondingly, these gravitational-wave events offer a new observational tool with which to probe the evolution and enrichment of galaxies over cosmic time. This complementarity brings unique opportunities for synergies and collaboration.

The aim of this meeting is to i) get communities together and foster interaction and exploration and ii) identify future opportunities and start new collaborations. This will be a strongly interactive workshop, with large part of the program reserved for discussions, unstructured interaction and breakout discussions.

Intensifying this cross-topical conversation is timely. We now have more than one hundred confirmed gravitational-wave observations of merging double compact objects, with potentially hundreds more revealed in the ongoing LIGO-Virgo-KAGRA observing run. As we speak, the IR imaging and spectroscopic capabilities of the JWST are revolutionizing the field of early galaxy evolution and chemical enrichment, and the next generation of large spectroscopic galaxy surveys is about to start. Discussion and activities undertaken at the meeting can thus seek to leverage this growing body of cutting edge data, while also defining the questions and methodologies to be explored with the next generation of spectroscopic galaxy surveys and gravitational-wave detectors.

Rare Gems in Big Data

Meeting Dates: 2024 May 20 - 23
Meeting Location: Tucson, AZ, USA
Abstract Deadline: 2024 Mar 1
Registration Deadline: 2024 Apr 19
Room Reservation Deadline: 2024 Apr 26

Main topics:

Surveys, time-domain and multi-messenger astrophysics, galaxies, cosmology, Milky Way and nearby galaxies, stellar populations, exoplanets, Solar System objects, techniques and tools.

Introduction

NOIRLab was established in 2019 to enable and share breakthrough discoveries in astronomy and astrophysics with state-of-the-art ground-based observatories, data products, and services for a diverse and inclusive community. As part of this mission, we are happy to announce the first in a regular NOIRLab conference series, on the topic of Rare Gems in Big Data.

Discoveries of rare gems in large astrophysical surveys have the potential to transform our understanding of the Universe across a broad range of science areas, such as the Milky Way and its halo, transients and variables, moving objects, planetary systems, and multi-messenger astronomy. Such discoveries, however, will be driven not only by the available data but also by the tools and infrastructure available to mine them. The motivation for this four-day NOIRLab conference is to explore the discovery space enabled by ongoing and upcoming astrophysical surveys (DESI, Rubin/LSST etc.) and the tools and techniques needed to find rare gems in them, including anomaly detection, citizen science, and AI & machine learning. We will also highlight the importance of spectroscopic and photometric follow-up observations and the services and tools developed by NOIRLab and others such as data archives, science platforms, and real-time astronomy systems.

The conference will feature talks by experts in the field to give background and set context, sessions designed for discussion and active engagement by participants, and live demos with opportunities for participants to try out new techniques.

The gems within the data are ready to shine brightly at this unparalleled gathering of astronomical minds.

Cosmic Ray Feedback in Galaxies and Galaxy Clusters

Meeting Dates: 2024 May 26 - Jun 16
Meeting Location: Aspen Center for Physics, Aspen, Colorado, USA

Understanding the processes underlying galaxy formation is one of the most important challenges in astrophysics. Unresolved questions include the disconnect between the short time scale of gas collapse on small scales and the long time scale for galaxy evolution, as well as the mechanism responsible for ejecting mass, momentum, and energy out of galaxies (or preventing their infall) in a way that matches the observed scaling relations. Recent progress in the field of astrophysical feedback strongly suggests that relativistic particle populations called cosmic rays may play a crucial role in controlling these processes in and around galaxies and galaxy clusters. However, the strength of cosmic ray feedback depends very sensitively on the dynamical coupling of cosmic rays to the plasma, a complete understanding of which will require novel plasma physics insights. Connecting detailed simulations to multi-frequency and multi-messenger observations will be of paramount importance for elucidating the underlying physics. Hence, the goal of this workshop is to bring together an interdisciplinary group of scientists studying plasma physics, cosmic ray propagation in the Milky Way, high-energy astrophysics (embracing radio, X-ray, and gamma-ray astronomy), galaxy formation, and evolution of galaxy clusters in order to learn from each other, facilitate collaborations among the participants, and advance the field into an era of predictive galaxy formation.

The X-ray Mysteries of Neutron Stars and White Dwarfs

Meeting Dates: 2024 Jun 5 - 7
Meeting Location: ESAC, Madrid, Spain
Registration Deadline: 2022 Sep 10

The X-ray emission from neutron stars and white dwarfs has been a subject of extensive research, unveiling unique insights into the high-energy phenomena occurring within these compact stellar remnants. In this meeting, we gather experts from various disciplines to delve into the latest advancements in understanding the X-ray emission processes, its origin, and the astrophysical implications associated with neutron stars and white dwarfs.

We will explore the diverse X-ray emission mechanisms, ranging from thermal emission due to accretion processes, magnetic fields, and nuclear reactions, to non-thermal emission originating from particle acceleration and magnetic reconnection events. These mechanisms provide crucial insights into the physical conditions and dynamics present in the extreme environments surrounding neutron stars and white dwarfs.

The X-ray spectra and timing properties will be discussed in detail, enabling a deeper understanding of the underlying emission mechanisms and the associated astrophysical phenomena. Spectral analysis techniques will shed light on the composition, temperature distribution, and physical parameters of the emitting regions. Furthermore, timing studies will reveal periodic and aperiodic variability, aiding in the characterization of rotational dynamics, accretion phenomena, and potential gravitational wave signatures.

In addition, we will explore the role of X-ray emission in the context of binary systems, investigating the interactions between compact objects and their stellar companions. X-ray binaries, including pulsars and cataclysmic variables, provide unique opportunities to study the accretion processes and the influence of intense magnetic fields on the X-ray emission.

Finally, we will discuss the implications of X-ray studies for our broader understanding of astrophysics. The X-ray emission from neutron stars and white dwarfs offers invaluable insights into compact object formation, stellar evolution, and the interplay between magnetic fields, radiation, and matter in extreme conditions. Synergies with radio, infrared, optical, gamma-rays and multi-messenger studies will be looked at, fostering interdisciplinary discussions and collaborations, encouraging the exchange of ideas. By collectively unraveling the high-energy mysteries, we strive to advance our understanding of these enigmatic stellar remnants and their impact on the cosmos as a whole.

Abstract (contribution talks) Deadline: 2024 Mar 11
Abstract (posters) Deadline: 2024 Apr 10
Early Registration Deadline: 2024 Apr 10
Registration Deadline: 2024 May 17

Following the success of the previous two conferences on supernova remnants in 2016 and 2019, a consensus was reached to hold regular meetings on the topic. Following delays due to COVID-19 pandemic, the Institute for Astronomy, Astrophysics, Space Applications & Remote Sensing of the National Observatory of Athens is happy to invite you to "Supernova Remnants III: An Odyssey in Space after Stellar death" on the beautiful island of Crete, the home of the mythical inventor and artisan Deadalus, as well as Icarus, Theseus and the Minotaur.

The conference will build upon spectral and imaging observations from radio to gamma-ray wavelengths of SNR blast waves, pulsar wind nebulae and SN ejecta and their interpretation through theoretical models and numerical simulations. The goals of the meeting are understanding the evolution of SNe, SNRs and their interaction with interstellar gas, elucidating the physical processes that govern shock waves and relativistic plasmas, and inferring characteristics of supernova explosions from SNR observations.

We will focus on narrowing the gap between observations and theories with the help of powerful new observing facilities and increasingly detailed and realistic numerical simulations. New understanding of the nature of supernova remnants and processes that occur there offers new insights into the role of SNRs in the structure and evolution of galaxies and the nature of supernova explosions.

Looking forward to seeing you in Crete!

360° approach to Common Envelope Evolution: From Binary Progenitors to Remnants

Meeting Dates: 2024 Jun 10 - 14
Meeting Location: Barcelona, Spain
Registration deadline: 2024 Feb 1

Common envelope evolution (CEE) is one key aspect of binary stellar evolution. Due to its high complexity, it is also the least understood, as current computational and theoretical approaches cannot describe the full process from the initial evolution of the progenitor binary system to unstable mass transfer, dynamical ejection (astrophysical transient), and final evolution of the remnant system. The goal of this workshop is to stimulate new collaborative research in this field by combining theory, simulations, population synthesis, and observations. To do this, we aim to review the state of the art for each CE stage, identify the main challenges, and, through discussions, envisage a strategy to approach them from a multi-disciplinary perspective. The full list of science topics can be found here.

Due to the highly interactive format of the workshop, we encourage in-person attendance, although online participation will also be possible. Registration can be done through the workshop's website, where you can also find the preliminary program, and additional information about the venue. The relevant dates for this workshop are explained here. Because of its interactive nature, the workshop will have a limited number of participants, which will be notified on the 1st of March 2024.We encourage early registration and reservation of accommodation and travel since economic hotels and flights fill in very rapidly in Barcelona in the summertime.The organization offers funds to cover the accommodation expenses for a limited number of participants. If you need financial support, please contact the SOC.

AGN across Continents

Meeting Dates: 2024 Jul 8 - 12
Meeting Location: Durham, UK
Abstract Deadline: 2023 Dec
Registration Deadline: 2024 Mar/Apr

This scientific workshop will explore current understanding of AGN populations, with a particular focus on current and future observational surveys. The primary scientific questions to be addressed are:

  1. How can we establish a complete census of black hole growth across cosmic time (including the highest redshift AGN) and what does this tell us about how and when supermassive black holes form and grow?
  2. What can multi-wavelength surveys tell us about different physical components of AGN and what implications does this have for a standard/unified model or evolutionary model of AGN? For example: obscured vs. unobscured AGN; red vs. blue quasars; 'radio quiet' vs. 'radio loud' AGN. This could include understanding the information we need from the different physical components of an AGN (e.g., obscuring torus, narrow line region, broad line region, jets, etc.).
  3. What are the properties of the host galaxies of different AGN populations and what does this tell us about how galaxies and AGN influence each other?
  4. What are the different data, observational techniques, and analysis methods we need to accelerate progress in answering these questions over the coming decade? This could include: exploiting SKA and its pathfinders; utilising current and forthcoming large-scale photometric/spectroscopic surveys; placing new constraints on magnetic fields; and applications of machine learning.
The scope of this workshop covers observational and theoretical work across the full wavelength range that tackle these scientific questions.

A parallel objective to the scientific content, is to build research connections between the European and African continents. Towards this, there will be substantial financial support to enable participation from astronomers based in Africa, who might otherwise be unable to attend the workshop. In conjunction with the scientific programme, we will hold dedicated activities before, during, and after the workshop to develop collaboration between the different scientific communities, and provide early career researchers with peer networking opportunities.

We anticipate a strong showcase of work that is of strong interest to both the European and African communities. For example, results from SKA pathfinder telescopes such as LOFAR, e-MERLIN, JVLA, and MeerKAT, in addition to telescopes such SALT in South Africa and H.E.S.S. in Namibia. Whilst the focus is on European-African collaboration, scientists from everywhere are welcome to participate.

The workshop will be limited to around 80 participants. Selection will be based on the quality of abstract submissions for talks or posters, and their alignment to the focus of the meeting. Consideration will also be made to a strong representation from African astronomers, to ensure a balanced view of AGN science across the continents.

Costs and Financial Support

The anticipated conference fee is around £350 (details to be confirmed later).

We have a substantial (but finite) budget to support scientists coming from Africa. This could cover, up to and including all travel and accommodation costs, plus a fee waiver. Preference for financial support will be given to those most in need, and to early career researchers. Applicants should indicate in their form, the level of financial support they would require to attend the workshop (e.g., travel, accommodation, fee waiver, complete costs, etc.).

Multi-messenger Transients from Binary Mergers

Meeting Dates: 2024 Aug 4 - 25
Meeting Location: Aspen, Colorado, USA

The first joint gravitational wave and electromagnetic detection of the binary neutron star GW170817 marked the dawn of the multi-messenger era with GWs. This watershed event opened a new window to study phenomena such as heavy element nucleosynthesis, black hole formation, the Universe's expansion rate, the equation of state of dense matter, and the intricate dynamics of relativistic jets. These profound inquiries have reignited interest in investigating similar physical processes at play in black hole-neutron star mergers and core-collapse supernovae. This endeavor necessitates the development of predictive models in anticipation of forthcoming observations in 2024 by LIGO-Virgo-KAGRA, Rubin Observatory, and future observation campaigns, that will transform the field of high-energy astrophysics transients. The primary goal of this workshop is to bring together physicists with diverse backgrounds in both theoretical and observational expertise within the domains of electromagnetic, gravitational wave, and particle emissions. Collectively, they will engage in collaborative efforts to identify and investigate pathways for tackling the pivotal scientific questions at the core of this rapidly evolving field.

IAU Symposium 392 — Neutral Hydrogen in and around Galaxies in the SKA Era

Meeting Dates: 2024 Aug 13 - 15
Meeting Location: Cape Town, South Africa

As the long term reservoir of fuel for star formation, knowledge of the neutral hydrogen (HI) properties of galaxies is essential to fully understand the build-up of the stellar mass and evolution of galaxies. With next-generation radio telescopes opening new observational frontiers in the study of HI, we can, for the first time, follow the HI emission from galaxies across cosmic time. The unprecedented quality of the SKA Observatory precursor and pathfinder telescopes provides resolved HI detections of large samples of galaxies beyond the local Universe, giving a clearer view of the cycle of gas acquisition and loss, storage and consumption. The HI scaling relations defined at z=0 are now being extended over billions of years of lookback time, yielding new inputs, as well as benchmarks to be reproduced, for the cosmological simulations of galaxy formation and evolution. As we enter the SKA era, HI observations are joining the extragalactic census in a way that has not been possible until now. This proposed IAU symposium will bring together the observational and theoretical communities to build a more complete understanding of the life cycle of galaxies, which better incorporates the information from HI observations that has often been previously missing from our multi-wavelength view of galaxy evolution.

Key Topics:

  • HI in the life-cycle of galaxies
  • Connecting simulations of HI to observations
  • An unbiased and resolved view of HI in the local Universe
  • Evolution of HI galaxy scaling relations across cosmic time
  • Constraining our cosmological model with HI observations
  • Environmental processes as traced by HI
  • The smallest galaxies as revealed by their neutral gas content

For additional questions, please see the conference website.

I-HOW/COSPAR Workshop: A New Era of High-Resolution X-Ray Spectroscopy

Meeting Dates: 2024 Aug 19 - 30
Meeting Location: Fudan University, China
Registration deadline: 2024 Mar 22

Warm and hot astrophysical plasmas are ubiquitous in the Universe, e.g. stellar coronae, hot gas in supernova remnants, ionized outflows running away from black holes, hot atmosphere of individual galaxies and galaxy assemblies, and warm-hot intergalactic medium in the cosmic web filaments. Characteristic emission and absorption spectral features in high-resolution X-ray spectroscopy provide powerful diagnostics to quantify the physical properties of the ionized plasmas, including temperature, density, abundance, kinematics, etc. These physical properties are essential to advance our knowledge of the formation and evolution of the Universe.

In the past few decades, high-resolution X-ray spectra have been sourced from the grating spectrometers aboard Chandra and XMM-Newton. In the next decade, we will enter a golden era for high-resolution X-ray spectroscopy, when most of the next-generation X-ray space observatories will have high-resolution spectrometers aboard, such as XRISM/Resolve, Athena/X-IFU, and proposed missions like HUBS, Arcus, LEM, etc. All these missions will provide a large number of high-resolution X-ray spectra.

The main goal of this I-HOW/COSPAR workshop is to facilitate the learning of high-resolution X-ray spectroscopy for early-career scientists in the Asia-Pacific countries. We will invite experts to teach:

  • Current high-resolution X-ray spectrometers and archival databases;
  • Data reduction and analysis skills on high-resolution X-ray spectra,
  • Astrophysical plasma models and the underlying atomic data,
  • The next generation of high-resolution X-ray spectrometers,
  • Writing and evaluating observational proposals.
We will provide hands-on exercises for the learners.

AGN Feedback and Star Formation Across Cosmic Scales and Time

Meeting Dates: 2024 Sep 2 - 6
Meeting Location: Sirolo, Italy

We are pleased to announce the first of a series of conferences on Astrophysics and Space Science in Marche, entitled "AGN Feedback and Star Formation Across Cosmic Scales and Time" which will be held at the historical theater of Sirolo, Italy, on September 2-6, 2024.

Scientific rationale

The star-formation properties of galaxies and the central supermassive black holes that they host follow a tight co-evolution. Current structure formation models invoke Active Galactic Nucleus (AGN) feedback via quasar or radio modes at the high stellar mass ends, as well as feedback from supernovae at low stellar masses, to explain the observed number density of galaxies as a function of stellar mass and redshift. However, despite decades-long efforts both simulations and observations still struggle to reach a consensus on the physical mechanisms regulating star formation and feedback across all scales (from sub-parsec to mega-parsec) and across cosmic history (from the local universe to the first galaxies). The advancements of hydrodynamical and semi-analytical simulations in terms of improved physically motivated models, code efficiency, and hardware for HPC infrastructures now allow us to reach unprecedented numerical accuracy, but the sensitivity leap in recent and current observations is further challenging our understanding of galaxy formation in a cosmological context. The conference will gather major experts to review the recent advancements in the field in the context of multi-wavelength observations and their comparison with theoretical and numerical models.

Key Science topics that will be covered:

  • Star formation across cosmic epochs
  • Quenching of star formation in galaxies
  • Physics of star formation and feedback from supernovae and AGN in simulations/li>
  • High resolution imaging and spectroscopy of AGN feedback, inflow/outflows and star formation (e.g., ALMA, JWST, MUSE, XRISM, etc.)
  • AGN feedback in clusters and dense environments
  • Theoretical and observational aspects of the formation and evolution of super massive black holes
Confirmed invited speakers:

David Alexander (Durham University); Marcella Brusa (University of Bologna); Adam Carnall (Royal Observatory, Edinburgh); Françoise Combes (Observatoire de Paris); Tiziana Di Matteo (Carnegie Mellon University); Roberto Maiolino (University of Cambridge); Brian McNamara (University of Waterloo); Raffaella Morganti (Kapteyn Institute, Groningen); Valeria Olivares (University of Kentucky); Annagrazia Puglisi (University of Southampton); Debora Sijacki (University of Cambridge); Linda Tacconi (MPE); Sylvain Veilleux (University of Maryland); Katherine Whitaker (UMass); Feng Yuan (Fudan University)

Binary and Multiple Stars in the Era of Big Sky Surveys

Meeting Dates: 2024 Sep 9 - 13
Meeting Location: Litomyšl, Czech Republic
Early registration deadline: 2024 May 1
Late Registration deadline: 2024 Jul 1
Abstract Submission deadline: 2024 July

Most stars in our Universe live in Binary and multiple systems. Understanding these objects is critical for practically all fields of astrophysics. The presence of a companion significantly alters the evolution of a star and results in a plethora of unusual objects including type Ia supernovae, symbiotic stars, classical novae, or post-common-envelope systems. Observations of the binary stars enable us to directly determine masses, radii, and luminosities of stars. These are necessary inputs for all models of stellar structure and evolution. The presence of binary and multiple systems affects all galactic environments including stellar associations, open and globular clusters.

The field of binary systems significantly benefits from numerous all-sky surveys and satellite missions which are primarily focused on exoplanets or pulsating stars. The unprecedented precision of the satellite data revolutionized research of binary stars. Numerous fine effects are being routinely observed and must be taken into account in the modeling. The continuous satellite photometry led to the detection of long-period eclipsing binaries and multiply-eclipsing multiple systems. The study of binaries also benefits from a simultaneous analysis of different types of observations including radial velocities, line profiles, multi-color photometry, astrometry, or polarimetry. In spite of substantial progress in the field there are still many open questions. Those include the formation of close binaries and multiple systems, the common-envelope evolution, the magnetic dynamo, and activity in binary stars or stellar mergers.

The scientific meeting will be organized in the city of Litomyšl, Czech Republic, on the week of September 9 - 13, 2024. The city will be honouring Zdenek Kopal, one of the foremost investigators of binary stars who was born in this city in 1914. A similar, smaller-scale conferences in the same city took place in 2004 and 2014.

First Results from the SRG/eROSITA All-Sky Survey: From Stars to Cosmology

Meeting Dates: 2024 Sep 15 - 20
Meeting Location: Garching, Germany
Abstract deadline: 2024 May 31
Early Registration deadline: 2024 Jul 31

In little more than half a century, X-ray astronomy has established itself as a fundamental domain of observational astrophysics. X-rays probe the hot and energetic components of the Universe, encompassing, among others, the million-degree coronae of stars, the remnants of supernovae, the ultra-dense matter in neutron stars, the immediate surroundings of black holes, the plasma filling galaxy clusters — the most massive objects in the Universe.

The new X-ray telescope eROSITA launched successfully on July 13, 2019, on board the Russian/German X-ray mission Spektr-RG (SRG). After commissioning and a successful performance verification program, eROSITA has started mapping the entire sky at unprecedented depths. Before being placed into safe mode on February 26, 2022, eROSITA completed 4.4 all-sky surveys. As in any other astrophysics domain, the eROSITA all-sky surveys unlock large swathes of discovery space, provide large statistical samples to study various classes of objects, and explore sufficiently large volumes to serve as cosmological tools for the study of the Universe as a whole. Serendipitous scientific highlights include an X-ray flash from a nova, quasi-periodic eruptions, tidal disruption events, and the eROSITA bubbles. The high sensitivity, large field of view, and high survey efficiency of eROSITA are revolutionizing X-ray astronomy: The first all-sky survey includes in the Western Galactic Hemisphere, among others, more than 12.000 clusters of galaxies, 700.000 Active Galactic Nuclei, and 180.000 stars or compact stellar objects. This exceeds the total number of previously discovered celestial X-ray objects since the dawn of X-ray astronomy.

This conference follows the public data release of the first all-sky survey, including source catalogs of point-like and extended sources, images, spectra, light curves, and X-ray photon events. We invite presentations of the first scientific results driven by the international community. We plan to cover the following topics:

Galaxy Clusters and Cosmology:

  • Physical properties of distant and nearby galaxy clusters, scaling relations
  • Clusters as tracers of the large-scale structure of the Universe
  • Tests of cosmological models with cluster statistics
  • Theory and simulations of structure formation
Active galactic nuclei and galaxy evolution:
  • Evolution and properties of the AGN population
  • AGN as tracers of large-scale structure
  • Extreme sub-populations (high redshift, high luminosity)

Galactic compact objects, stars, and planets

  • Heliosphere
  • Active stars: physics and population studies
  • Cataclysmic variables and X-ray binaries
  • Isolated neutron stars
  • ULX and X-ray sources in nearby galaxies

The Transient X-ray sky

  • Tidal Disruption Events
  • Quasi-periodic eruptions
  • Gamma-ray bursts and afterglows
  • Galactic X-ray transients
  • Gravitational Waves and other multi-messenger counterparts

Diffuse X-ray emission

  • Hot plasmas in the Milky Way, LMC, and SMC
  • Circum-Galactic Medium
  • Supernova Remnants
  • Cosmic X-ray background and its fluctuations
  • High-energy physical processes in the solar neighborhood

Synergies with multi-wavelength surveys and multi-messenger probes

We hope that the attendees will enjoy the famous Oktoberfest of Munich, which is right after the conference.

IXPO: International X-ray POlarimetry Symposium

Meeting Dates: 2024 Sep 16 - 19
Meeting Location: Huntsville, AL, USA
Abstract and Registration deadline: TBA

Decades after the pioneering launch of the first X-ray polarimeter onboard OSO-8, the field of X-ray polarimetry is experiencing a major resurgence, catalyzed by the launch of the Imaging X-ray Polarimetry Explorer (IXPE) -- the first dedicated astrophysics mission for X-ray polarimetry. During the initial 2-year prime mission phase IXPE has increased the number of X-ray polarization detections from one to a few dozen, with significant consequences for our understanding of high-energy astrophysical objects. The opening of the first General Observer period in early 2024 promises to expand on these discoveries to new source classes and science questions.

This conference will be an opportunity to explore the wide range of science enabled by X-ray polarimetry provided by IXPE and other missions such as XPoSAT and PolarLight. It will include sessions focused on active galactic nuclei, blazars, accreting neutron stars and stellar black holes, supernova remnants, magnetars, and pulsar wind nebulae, as well as future mission concepts. This conference aims to foster inclusivity and collaboration within the scientific community by providing sessions on X-ray polarimetry data analysis, and we invite researchers of all backgrounds to engage in the frontier of high energy polarimetry. As a highlight, the workshop will coincide with a celebration of the awarding of the Rossi Prize to Martin Weisskopf, Paolo Soffitta, and the IXPE team, to be held at the nearby U.S. Space and Rocket Center.

Accurate Flux Calibration in the Era of Space Astronomy and All-Sky Surveys Workshop

Meeting Dates: 2024 Oct 22 - 25
Meeting Location: Baltimore, MD, USA
Abstract Deadline: 2024 May 31
Registration Deadline: 2024 Sep 19

Advances in space telescope technology and all-sky surveys are driving the need for more precise and accurate flux calibration across the observable spectrum. The Space Telescope Science Institute is hosting a workshop in October 2024 to evaluate the current state of flux calibration for both ground-based and space observatories.

Workshop Objectives:

  • Identify issues affecting cross-mission calibration and their impact on the Hubble, Webb, and Roman Space Telescopes as well as surveys like Gaia and Rubin.
  • Improve the consistency of flux calibration across the electromagnetic spectrum, with an emphasis on the ultraviolet to the mid-infrared.
  • Address the limiting factors for calibration between ground-based and space observatories.
  • Improve and assess the relative strengths and weaknesses of the models used for different classes of standards.
Workshop Significance: STScI last hosted a calibration workshop over a decade ago. A workshop planned for March, 2020, did not take place due to the pandemic. With new telescopes, new technologies, and new scientific requirements, the need has grown for the astronomy community to meet, assess the current state of the art, and develop new collaborations to improve our current flux calibration. For additional questions, please see the conference website.
