Mapping the X-ray Sky with SRG: First Results from eROSITA and ART-XC

Meeting Dates: 2020 March 16 - 20 (POSTPONED! Date TBA)
Meeting Location: Garching, Germany
Abstract deadline: 2020 Jan 5 (EXTENDED!!!)
Early registration deadline: 2020 Feb 8

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.

Successfully launched in July 2019, after more than a decade of development, the Russian-German Spectrum-RG (SRG) mission will contribute to the X-ray exploration of the Universe by performing eight all-sky surveys, each lasting half a year, with its two scientific instruments: eROSITA, the German-built telescope array operating between ~0.3-8 keV, and ART-XC, the Russian-built hard-X-ray focusing telescope array, operating between ~3-30 keV.

As in any other astrophysics domain, the SRG all-sky surveys will unlock large swathes of discovery space, provide large statistical samples to trace the cosmic evolution of various classes of objects, and explore sufficiently large volumes to serve as cosmological tools for the study the Universe as a whole. In particular, the high sensitivity, large field of view, and high survey efficiency of eROSITA is bound to revolutionize X-ray astronomy: within just the first year of operation it will discover about as many new celestial X-ray objects as have been discovered from 1962 until today.

The goal of the next international SRG conference (the third in a series, and the first after the SRG launch) is to discuss the state of the art in the different scientific areas addressed by the mission, present to the community the first results from eROSITA and ART-XC, and explore the synergies with surveys and observations at other wavelengths.

The meeting plans to cover the following topics:

  • Galaxy clusters and cosmology
    • Physical properties of clusters and groups of galaxies
    • Large scale structure of the Universe
    • Clusters as cosmological tools
  • Active galactic nuclei
    • Evolution and properties of the AGN population
    • Quasars at high redshift
    • AGN as tracers of large scale structure
  • Galactic compact objects, stars and planets
    • X-ray emission from planets and comets
    • X-ray stellar populations of the Milky Way
    • 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
    • Gamma-ray bursts and afterglows
    • Galactic X-ray transients
  • Diffuse X-ray emission
    • Cosmic X-ray background and its fluctuations
    • Galactic Ridge X-ray Emission
    • Hot ISM in the Milky Way, LMC and SMC
    • Supernova remnants
  • Synergy with multi-wavelength surveys

The 9th Fermi Symposium

Meeting Dates: 2020 March 29 - April 3[POSTPONED! Tentative Date June 22 - 26]:
Meeting Location: Johannesburg, South Africa

This symposium follows previous Fermi Symposia at Stanford, CA (February 2007), Washington, DC (November 2009), Rome, Italy (May 2011), Monterey, CA (November 2012), Nagoya, Japan (October 2014), Arlington, VA (November 2015), Garmisch-Partenkirchen, Germany (October 2017), and Baltimore, MD (October 2018).

The two Fermi instruments have been surveying the high-energy sky since August 2008. The Large Area Telescope (LAT) has discovered more than a thousand new sources and many new source classes, bringing the importance of gamma-ray astrophysics to an ever-broadening community. The LAT catalog includes supernova remnants, pulsar wind nebulae, pulsars, binary systems, novae, several classes of active galaxies, starburst galaxies, normal galaxies, and a large number of unidentified sources. Continuous monitoring of the high-energy gamma-ray sky has uncovered numerous outbursts from a wide range of transients. Fermi LAT's study of diffuse gamma-ray emission in our galaxy revealed giant bubbles shining in gamma rays. The direct measurement of a harder-than-expected cosmic-ray electron spectrum may imply the presence of nearby cosmic-ray accelerators. LAT data have provided stringent constraints on new phenomena such as supersymmetric dark-matter annihilations as well as tests of fundamental physics. The Gamma-ray Burst Monitor (GBM) continues to be a prolific detector of gamma-ray transients: magnetars, solar flares, terrestrial gamma-ray flashes and gamma-ray bursts at keV to MeV energies, complementing the higher energy LAT observations of those sources in addition to providing valuable science return in their own right.

All gamma-ray data are made immediately available at the Fermi Science Support Center. These publicly available data and Fermi analysis tools have enabled a large number of important studies. We especially encourage guest investigators worldwide to participate in this symposium to share results and to learn about upcoming opportunities.

This meeting will focus on the new scientific investigations and results enabled by Fermi, the mission and instrument characteristics, future opportunities, and coordinated observations and analyses.

Early Registration Opens: 2019 Dec 2
Early Registration Deadline: 2020 Jan 17
Late Registration Deadline: 2020 April 24
Onsite Registration Deadline: 2020 April 27

Since its launch in November 2004, the Neil Gehrels Swift Observatory has provided a unique suite of multi-wavelength instruments to both discover and follow-up a wide range of transients and variable sources. To celebrate the 15th anniversary of the Swift launch, we are organizing a conference to explore the future landscape of panchromatic transient studies. The next decade promises to be rife with discoveries, with new and upgraded facilities spanning the entire electromagnetic spectrum (e.g., SVOM, eROSITA, LSST, SKA) and beyond (LIGO/Virgo, IceCube). This workshop will focus on the critical role enabled by multi-wavelength studies in this period. The meeting will be organized around a series of key open questions, including:

  • What powers newly discovered stellar explosions such as superluminous supernovae and fast luminous/blue optical transients?
  • Are binary neutron star mergers the (sole) progenitors of short gamma-ray bursts?
  • From where does the emission arise in tidal disruption events, and how can we use these sources to measure black hole properties (mass, spin)?
  • What are the cosmic sources of high-energy neutrinos?
  • How do neutron stars achieve super-Eddington luminosities, and why are ULXs sometimes transient?
  • What powers the non-thermal emission in classical novae, and are they potential progenitors of type Ia supernovae?
  • What determines whether a massive star will explode as a long gamma-ray burst or a core-collapse supernova?

Extragalactic jets on all scales -- launching, propagation, termination

Meeting Dates: 2020 June 15 - 19 [POSTPONED! Date TBA]
Meeting Location: Max Planck Institute for Astronomy, Heidelberg, Germany
Early registration deadline: 2020 March 30
Registration deadline: 2020 April 30

Energetic and collimated beams of plasma launched from the centre of galaxies have fascinated the community for a century. In spite of the advancement in observational and theoretical modelling techniques, many aspects regarding the detailed physics of extra-galactic jets remain not fully understood. This conference aims to push forward our understanding of extra-galactic jets bringing together experts from theory and observations.

The main focus shall be on the theoretical side. One major aim of this conference is to demonstrate recent advances in the multi-scale numerical modeling of jets and to discuss strategies for how to better constrain simulations with multi-wavelength and high-resolution observational data. Another focus shall be the universality of jet properties and understand what we can learn from other jets sources such as non-relativistic jets or GRBs.

The conference addresses the astrophysics across all scales of the jets from :

  • the launching scale that governs the jet energetics and matter content
  • the propagation scale involving magnetic dissipation, particle acceleration and non-thermal radiation, jet stability and variability
  • the termination scale that is essentially connected to IGM and ICM feedback and the FRI/FRII jet power

Present and future sensitive radio facilities, such as VLA, LOFAR, EHT, and SKA, together with those extending the coverage over a full multiwavelength range, will be crucial for unraveling the jet physics at all spatial scales. This conference should be a platform to discuss state-of-the-art astrophysical approaches which can successfully bridge between numerical simulations, theoretical models, and multi-wavelength/multi-messenger observations.

In particular we would appreciate contributions on the following topics:

  • Jet launching : GR-MHD simulations, launching site
  • Jet stability and variability
  • Jet energetics : heating, dissipation
  • Jet termination : AGN Feedback and ICM Heating
  • Particle acceleration mechanisms
  • Emission and polarization - observed and simulated
  • Essential observational inputs for theory
  • Universality of jet properties

Conference on Time Domain Astronomy in the High Redshift Universe

Meeting Dates: 2020 June 23 - 26: [POSTPONED! New date in Spring 2021 (TBA)]
Meeting Location: George Washington University, Washington, DC, USA
Early registration and Abstract deadline: 2020 February 28
Late Registration deadline: 2020 March 27

Meeting Topic:

The high redshift Universe (z > 6) encompasses the time when Hydrogen was re-ionized, when the first generation of stars were born, lived and died, and when the first black holes were formed and began growing into active galactic nuclei (AGN). This early period is expected to be rich with time variable objects including Supernovae, Gamma-Ray Bursts, Quasars and Black Hole Mergers. The Conference will explore the required observational capabilities to study high redshift transients and how their multi-messenger studies can be used as probes of the formation of the modern Universe.

Meeting Logistics:

This will be a four-day meeting. The first three days (June 23-25) will be a mix of invited and contributed talks, with a panel discussion and posters. The fourth day (June 26) we will make rooms available for participants to hold self-organizing discussions, workshops and meetings that focus on specific conference related topics, future facilities and other related discussions.

Limited support for graduate students and childcare will be available.

BeXRB 2020

Meeting Dates: 2020 July 27 - 29 [POSTPONED! New date in 2021 (TBA)]
Meeting Location: Valencia, Spain
Abstract deadline: 2020 Feb 28
Registration deadline: 2020 Feb 28P

BeXRB workshops, with its 4th edition to be held in Valencia on July 27th-29th 2020, have become key meetings in the field. Aiming at giving place to a very broad set of topics and fields of research (related to Be stars in X-Ray Binaries and similar objects), and to create an atmosphere of knowledge sharing and discussion, the need of such a meeting with a ~3 year periodicity is encouraged by the great success of previous editions.

Be stars themselves still represent a challenge to modern astrophysics. When in binary systems, their observation and modelling do not only shed light into our knowledge of the peculiarities of Be stars, but also into a variety of topics of great interest, like physics of accretion, matter and light in extreme conditions, and massive binary star evolution as progenitors of NS-NS or NS-BH systems, primary targets of GW detection in the present times.

Therefore, the intensive study of these objects by the scientific community must keep at the good pace that we have witnessed in the last decade. BeXRB 2020 will try to contribute to push knowledge in the field, promote collaborations, and offer lots of networking options among scientists from very different fields of research.

Key topics:

  • Phenomenology of BeXRB transient outbursts in the X-ray domain
  • Transient outbursts as laboratories of accretion physics
  • Timing studies of Be/X-ray binaries
  • Transfer of mass: from decretion to accretion, observation and modelling
  • Multi-wavelength observations and their implications
  • Population studies: Be/X-ray binaries with white dwarfs and black holes, BeXRB population in external galaxies
  • The high-energy gamma-ray connection
  • Prospects in the light of current and future space missions and multimessenger astrophysics

Astronomy from the Moon: the next decades

Meeting Dates: 2020 March 18 - 19[POSTPONED! Date TBA]
Meeting Location: London, England
Registration deadline: 2020 Feb 3

Scientific discussion meeting organised by Professor Joseph Silk FRS, Professor John Zarnecki, Professor Ian Crawford and Dr Martin Elvis.

Observatory on the Moon

Low-frequency radio astronomy from the radio-shielded lunar far side can have a unique science impact on cosmology potentially at modest cost. The permanently shadowed lunar craters may offer advantages for passive cooling of infrared telescopes. This meeting will examine these and other potential uses of the Moon as a platform for astronomical observations and the policy implications.

The schedule of talks and speaker biographies are available at the conference website. Speaker abstracts will be available closer to the meeting. Recorded audio of the presentations will be available on this page after the meeting has taken place. Meeting papers will be published in a future issue of Philosophical Transactions of the Royal Society A.

Poster session

There will be a poster session at 17.00 on Wednesday 18 March. If you would like to apply to present a poster, please submit your title, your abstract (no more than 200 words and in third person), author list, name of the proposed presenter and authors' institutions to the Scientific Programmes team no later than Monday 3 February 2020. Please include the text 'Poster abstract submission' in the subject heading. Please note that places are limited and are selected at the scientific organisers' discretion.

The Physical Challenges of Astro-Statistics [CANCELLED! ]

Meeting Dates: 2020 March 9 - 13
Meeting Location: Sexten, Italy

Astrostatistics is developing fast as astronomy is confronted to huge volumes of data. This constitutes undoubtly a new era through a move from object- to data-driven astrophysics. The question that needs to be solved is the following: how can we reconnect statistical results obtained by automatic tools such as machine learning or hypothesis testing, with object-driven inferences derived from visual inspection, modelisation or numerical simulation? How do we reconcile a statistical, hence fuzzy, classification with the visual Hubble sequence of galaxies? How do we describe, synthetize, the data cubes (images + spectra) obtained by IFUs? How can we constrain a model of stellar evolution with the statistics of billions of stars? How do we characterize a scaling law in a 4-D or 10-D dimension parameter space?

In this workshop, we want to focus particularly on the connection between the tools and the astrophysics, between data analysis and science.

Invited speakers:

  • Stefano Andreon (INAF, Milano, Italy): Bayesian Physics.
  • Roland Bacon (CRAAL, Lyon, France): Hyperspectral Data: experience from MUSE.
  • Dovi Poznanski (Tel-Aviv University, Israel): Extracting Knowledge from Massive Spectroscopic Surveys.
  • Agnieszka Pollo (Jagiellonian University, Poland): Multivariate Analyses and Classification.
  • Stefano Cavuoti (INAF, Naples, Italy): Machine Learning in Astrophysics.
  • Laurent Eyer (Obs Geneva, Switzerland): Time Series from Gaia.
  • Michael Kuhn (CalTech, USA): Statistical models to study young star clusters and associations.

Gravitational Wave Open Data Workshop #3

Meeting Dates: 2020 May 26 - 27
Meeting Location: Silver Spring, Maryland[Changed to remote video conferencing software, see link for details]
Registration Opens: March 9, 2020 *attendance limited on first-come, first-served basis*

Advanced LIGO and Advanced Virgo are now observing the gravitational-wave sky with unprecedented sensitivity. To date, there have been over 50 potential gravitational-wave transients observed, and planned detector upgrades are likely to accelerate the pace of discovery in the coming years. This new window on the universe is providing insights on a range of topics, including compact body populations, cosmology, and fundamental physics.

LIGO and Virgo strain data from past observation runs and data snippets around discoveries are made publicly available at, along with associated software libraries. The LIGO and Virgo collaborations are hosting an Open Data Workshop to facilitate working with these data products. This workshop is the third edition of a series that began in 2018. It is intended for scientists and students who wish to learn about using gravitational-wave data and software in order to conduct research of their own. The workshop will provide a mixture of lecture style presentations and hands-on programming exercises, using publicly available gravitational-wave data and specialized software tools.
