Are AGN Special? The Environmental Dependence and Global Impact of AGN Activity

Meeting Dates: 2018 July 30 - August 3
Deadline for Abstract Submission: 2018 March 31

Powered by mass accretion onto super-massive black holes, Active Galactic Nuclei (AGN) are undoubtedly exotic phenomena. According to most theoretical models of galaxy formation, AGN have also had a profound impact on the way the Universe looks today. However, AGN activity is, in another sense, a common phenomenon: the finding that essentially all massive galaxies host a central supermassive black hole clearly indicates that these galaxies have all hosted AGN activity at some point during their lives. Are these AGN phases a special period in the lifetime of the galaxy that require specific environmental conditions, or are they simply a random event that can occur at any time in any galaxy?

The objective of this international workshop is to bring together observers and theorists to explore the environmental dependence and global impact of AGN activity. During the five days of the workshop we will investigate:

  • What host-galaxy properties facilitate AGN activity?
  • What larger-scale environments facilitate AGN activity?
  • Is the high-redshift Universe a special environment for AGN activity?
  • How do AGN shape the way the Universe looks?

X-Ray Skies with High-Res Eyes: Imaging the Cosmos with AXIS

Workshop Dates: 2018 August 6 - 7
Deadlines for Abstract Submission and Registration: 2018 July 20
Workshop Location, Washington, DC, USA

The "X-Ray Skies with High-Res Eyes" workshop will be held at the Carnegie Institution for Science's main building in downtown Washington, DC (1530 P Street NW). The purpose of this meeting is to explore the cutting edge astrophysics enabled by a high angular resolution X-ray observatory in the next decade, present the AXIS (Advanced X-ray Imaging Satellite) science case to the community, and solicit feedback. AXIS is a probe concept under study for submission to the 2020 Decadal survey. Compared to current high-resolution X-ray observatories, AXIS will have order-of-magnitude improvements in sensitivity, field-of-view and lower background and its rapid-slewing capability will support fast-response ToOs and other time domain science.

There will also be speakers from the AXIS team. The organizers are soliciting a limited number of contributed talks on topics related to high spatial resolution X-ray imaging and its connection with the broader astrophysical community.

The workshop will focus on AXIS science themes appropriate to the next two decades of astronomical X-ray research. Contributed talks on the capabilities of AXIS are solicited for topics ranging from (but by no means limited to):

    - Solar System & exosystem science 
    - The interstellar medium 
    - Star formation 
    - Planetary nebulae 
    - Nearby and high redshift galaxies 
    - Gravitational lensing 
    - Dual AGN 
    - Star formation and AGN growth in the high redshift universe 
    - The circumgalactic medium 
    - Supernova remnants 
    - X-ray binaries in nearby galaxies 
    - The outer regions of groups and clusters

Chandra Science Workshop on Accretion in Stellar Systems

Workshop Dates: 2018 August 8 - 10
Deadline for Oral and Poster Presentations: 2018 June 13
Deadline for Regular Registration: 2018 June 25 (Late registration available afterwards)
Workshop Location: Cambridge, Massachusetts, USA

The workshop aims to bring together people working on accretion, outflows and related processes in diverse astrophysical objects, from protostars to cataclysmic variables to super-Eddington accretion in stellar mass black hole and neutron star binaries. The focus will be to understand how accretion and ejection work, how they affect stellar evolution, what important issues remain unanswered, and what are likely to be the most promising future research directions. The workshop will cover theory, simulations and observations, spanning the time domain, the entire electromagnetic spectrum, gravitational waves and energetic particles. A special session dedicated to the late Jeff McClintock's legacy to the field will also be held.

Radionuclide Astronomy in the 2020's and Beyond (RA2020)

Workshop Dates: 2018 August 20 - 22
Workshop Location: Los Alamos, New Mexico, USA

The purpose of the RA2020 workshop is focused on determining the potential science goals in radionuclide astronomy for next-generation X-ray and gamma-ray missions. This will include identifying and prioritizing open astrophysical questions on astrophysical sources of radionuclides that can be addressed by next-generation missions. We will identify the astrophysical modeling and nuclear data needs to maximize the science from these missions. The workshop will also provide a forum within which the community can present and review the current state of knowledge in hard x-rays and gamma-rays from radioactive nuclei produced in astrophysical transients and identify challenges and opportunities for the field in the near future. RA2020 is sponsored by Los Alamos National Laboratory and Joint Institute for Nuclear Astrophysics - Center for the Evolution of the Elements.

The target audience includes astronomers and astrophysicists (observers, experimentalists, theorists), space mission scientists, nuclear and particle physicists (theorists and experimentalists in nuclear reactions, gamma production, and neutrino interactions), instrument developers, and other interested researchers including graduate students and recent PhD recipients.

Specific Goals of RA2020 include:

  1. Determine the constraints that next-generation telescopes can place on astrophysical sources of radionuclides;
  2. Identify the open problems that can be solved by these constraints;
  3. Identify the astrophysical modeling needs to take full advantage of the data from these next generation telescopes;
  4. Prioritize the modeling needs based on the demand to maximize mission scientific return;
  5. Identify the critical nuclear astrophysics data needs of NASA's current and near-term planned astrophysics missions;
  6. Prioritize those data needs based on the demand to maximize mission scientific return;
  7. Identify either the ideal properties of next-generation telescopes to maximize radionuclide astronomy science (based on the list of open problems) or determine the path needed to identify these properties.
  8. Develop strategies for community input to the Astro2020 Decadal Survey;
  9. Formulate a summary of prioritized needs to guide future NASA funding of the field.

The most important and valuable deliverable from RA2020 will be the Report summarizing the recommendations from the workshop. The Report will provide detailed findings on the critical astrophysical modeling and nuclear astrophysics data that are required to maximize the scientific return on NASA's current and near-term planned astrophysics missions and proposed priorities. The Report will be based on community input gathered at the workshop, discussions during workshop breakout sessions, and other solicited input deemed appropriate by the Scientific Organizing Committee (SOC). The Report will be prepared by the SOC and may also outline specific opportunities for high energy NASA missions, and articulate concrete actions by which the Agency can capitalize on the opportunities and mitigate challenges.

IAU Focus Meeting on "Radio Galaxies: Resolving the AGN Phenomenon" at the IAU General Assembly 2018

Meeting Dates: 2018 August 22 - 23
Early-bird Registration Deadline: 2018 January 31
Deadline for Regular Abstract Submission for Oral and Poster Contributions: 2018 February 28
Deadline for IAU Grant Submission: 2018 February 28
Deadline for Poster-only Submissions: 2018 May 31
Deadline for Regular Registration: 2018 June 30

Radio galaxies provide excellent laboratories to probe physical aspects, unification, and the cosmic evolution of Active Galactic Nuclei (AGN). Thanks to recent multi-wavelength observations we are now able to separate many different physical components of radio galaxies through imaging and spectroscopy. Observations from the radio to the X-ray range can probe the ejection of matter into the jet and monitor decades of jet evolution. Gamma-ray observations have shown that radio galaxies are detectable up to the VHE range, despite unfavorable jet alignment. We observe radio galaxies out to redshifts larger than z=5, which makes them important cosmological probes. Planck maps have provided us with new insights into the populations of radio galaxies and their distributions in space in the 30-900 GHz range, NuSTAR provides high-quality spectra in the hard X-ray range, the EHT has begun mapping to the event horizon of the central black hole, and the SKA, E-ELT and other future telescopes will open up a new and vast discovery space. This meeting will bring together multiwavelength observers and theorists to synthesize progress made over the last three years and define future directions.


  • Triggers of highly relativistic jets
  • Jet collimation
  • Radio galaxies as VHE photon emitters
  • Knots, hotspots and other structural features
  • The central engine
  • Radiative versus jet mode
  • Radio galaxy populations and statistics
  • Origin and evolution of radio galaxies
  • Interaction with the environment
  • Future telescopes' view on radio galaxies

The Gamma Cas Phenomenon in Be Stars

Meeting Dates: 2018 September 3 - 5
Deadline for Registration: 2018 June 15
Meeting Capacity: 50 persons
Meeting Location: Strasbourg, France

Gamma-Cas is the first identified Be star and one of the first extra-solar X-ray sources discovered. However, it soon became clear that its very hard and luminous X-ray emission was at strong variance with that observed from the bulk of Be stars. Galactic X-ray surveys, mainly those carried out by XMM-Newton, led to the discovery of a handful of Be stars with similar X-ray properties and sharing a narrow range of characteristics.

The origin of the outstanding X-ray emission of Gamma-Cas and its analogs is one of the most vexing issue in X-ray stellar astrophysics. Magnetic interaction between the early type star and the decretion disc compete with accretion scenarios to explain these outstanding features. Both explanations have deep astrophysical implications on massive star evolution.

The goal of the meeting is to inform the stellar community of the "Gamma-Cas" phenomenon and confront the different views put forward to explain this salient behaviour.

8th International Workshop on Astronomy and Relativistic Astrophysics - IWARA 2018

Meeting Dates: 2018 September 9 - 15
Deadline for Registration and Abstract Submission: 2018 June 30
Meeting Location: Ollantaytambo, Peru

Our understanding of the origin of the Universe, of its evolution and the physical laws that govern its behavior, as well as on the different states of matter that makes up its evolutionary stage, reached in recent years levels never before imagined. This is due mainly to the new and recent discoveries in astronomy and relativistic astrophysics as well as to experiments on particle and nuclear physics that made the traditional boundaries of knowledge on physics to be overcome. As a result we have presently a new understanding about the Universe in its two extreme domains, the very large and the very small: the recognition of the deep connections that exist between quarks and the cosmos.

The intimate relationship between quarks and the cosmos has motivated the organization of the series of international events known by the acronym IWARA. The event is the eighth in a series of meetings gathering scientists working on astroparticle physics, cosmology, gravitation, nuclear physics, and related fields.

Exploring the Hot and Energetic Universe: The Second Scientific Conference Dedicated to the Athena X-ray Observatory

Conference Dates: 2018 September 24 - 27
Deadline for Submission of Abstracts for Contributed Talks and Posters: 2018 February 23
Conference Location: Palermo, Sicily, Italy

Athena (the Advanced Telescope for High-Energy Astrophysics) will continue the series of large X-ray observatories inaugurated by Chandra and XMM-Newton, offering transformational capabilities in several key areas. It is the second large-class ESA mission (L2), and it is planned for a launch towards the end of the next decade, around 2029.

The Phase A is progressing at full speed, with intense work in the ESA Study Team, the Instrument Teams and industry with the definition of a mission design baseline over the next 12-18 months. The organization of the second conference on Athena will thus give the opportunity to discuss with the astrophysical community its prospective scientific impact, also in the light of possible future X-ray missions (eROSITA, XARM, Arcus, etc.), of synergies with multi-wavelength facilities that will be operational at the end of the next decade, and of the advent of multi-messenger astronomy.

Breaking the Limits 2018: Super-Eddington Accretion onto Compact Objects

Meeting Dates: 2018 October 1 - 5
Deadline for Abstract Submission: 2018 May 31
Deadline for Early Bird Registration: 2018 July 31
Late Registration: from 2018 August 1 and onsite
Meeting Location: Castiadas, Italy

Recent years have seen an increasing interest of the astronomical community on the topic of super-Eddington accretion on compact objects, which can apply to a variety of systems, such as supermassive black holes, black hole binaries, ULXs, neutron stars. Moreover, the possibility that the Eddington limit may be violated can have important implications for the related topics of black hole growth, galaxy evolution and AGN feedback.

After two years from the first edition of Breaking the Limits, we reconvene to discuss the advances made in the last two years. This workshop will be an opportunity to compare recent observations with state-of-the-art theoretical modeling of super-Eddington flows, and to discuss the cosmological implications of this regime of accretion.

The Multi-Messenger Astronomy: Gamma-Ray Bursts, Search for Electromagnetic Counterparts to Neutrino Events and Gravitational Waves

Meeting Dates:2018 October 7 - 14
Pre-registration Opens: 2018 May 1
Registration and Abstract Submission Open: 2018 June 1
Registration and Abstract Submission Close: 2018 August 7
Meeting Location: Nizhnij Arkhyz and Terskol, Russia

The international conference on this urgent topic will be held in Russia for the third time. The success of the first workshop held in October 2015 and the second conference held in October 2017 persuaded the organizers that such meetings arranged in locations of unique Russian Observatories - Special Astrophysical Observatory of RAS (SAO RAS), Baksan Neutrino Observatory of Institute for Nuclear Research of RAS (BNO INR RAS) and the International Observatory Peak Terskol - are well needed.

The scientific program covers a wide range of problems of the modern astrophysics including that of existence of quantum-chromodynimic (QCD) phase transition and matter states at high temperatures and densities. Such conditions are likely to be achievable only in astrophysical objects - collapsars of stellar mass, the objects whose formation is related with collapse and explosion of hot and dense cores of massive stars observable as gamma-ray bursts and supernovae. Solution of such problems demands development of methods combining optical astronomical observations and experiments with neutrino telescopes, cosmic-ray recording sets and detectors of gravitational waves.

The conference program will also include talks and discussion on the THESEUS (Transient High-Energy Sky and Early Universe Surveyor) mission concept, being developed by a large International collaboration involving also SAO and BNO. THESEUS aims at exploiting high-redshift gamma-ray bursts for getting unique clues to the Universe and, being an unprecedentedly powerful machine for the detection, accurate location and redshift determination of all types of gamma-ray bursts (long, short, high-z, under-luminous, ultra-long) and many other classes of transient sources and phenomena, at providing a substantial contribution to multi-messenger astrophysics and time-domain astronomy. Under these respects, THESEUS will show a beautiful synergy with the large observing facilities of the future, like E-ELT, TMT, SKA, CTA, ATHENA, in the electromagnetic domain, as well as with next-generation gravitational-waves (aLIGO/ aVirgo, KAGRA, ILIGO, Einstein Telescope, LISA) and neutrino detectors, thus enhancing importantly their scientific return. Moreover, it will also operate as a flexible IR and X-ray observatory, thus providing an even larger involvement of the scientific community.

Eighth International Fermi Symposium

Meeting Dates: 2018 October 14 - 19
Meeting Location: Baltimore, Maryland, USA

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), and Garmisch-Partenkirchen, Germany (October 2017).

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.
