From Chandra to Lynx: Taking the Sharpest X-ray Vision Fainter and Farther

Workshop Dates: 2017 August 8 - 10

Deadline for Submitting Abstracts: 2017 June 28

Deadline for Regular Registration: 2017 July 14

Workshop Location: Cambridge, Massachusetts, USA

Since 1999, the Chandra X-ray Observatory has provided unprecedented high-spatial resolution X-ray vision of the invisible universe. Together with its high-resolution X-ray spectroscopic capabilities, Chandra continues breakthrough studies of our universe from the distant supermassive black holes and the large-scale environments around galaxy clusters to stars and objects in our solar system. Lynx, formerly known as the X-ray Surveyor, is one of the large strategic mission concepts identified in the 2013 NASA Astrophysics Roadmap ("Enduring Quests, Daring Visions"). Lynx is the first future X-ray mission concept planning to match the spatial-resolution, and thus be a true successor to Chandra. The high-resolution X-ray imaging with a tremendous increase in sensitivity will allow Lynx to pursue multiple quests deeper into the invisible X-ray universe. This workshop seeks to leverage Chandra's legacy and maximize its impact on the development of Lynx science and design objectives. Lynx's Chandra-like spatial resolution, together with a tremendous increase in sensitivity will allow multiple quests deeper into the invisible X-ray universe.

Bursting Universe by Robots Eyes: Devoted to the 15th Anniversary of the MASTER Project

Meeting Dates: 2017 August 14 - 18

Meeting Location: Moscow, Russia

Twenty years ago it was realized that robotic observatories boost the capabilities of astronomical observations of non-stationary and short-lived phenomena in the Universe. Such facilities built throughout the world allowed to discover and study the prompt mission of the most powerful explosions the gamma-ray bursts. Hundreds of supernovae were detected as well which enabled to infer the existence of the energy of the cosmic vacuum. Additionally, the robotised telescopes discover thousands of new minor bodies of the solar system and many of exoplanets.

The first Russian robot-telescope MASTER was developed in 2002 and installed nearby Moscow. It appeared not only scientifically fruitful but also useful as an effective platform for methodology and technical studies devoted to optimise the use of small robotized telescopes of which the most essential is the unique software needed for automated multipurpose astronomical observations.

MASTER was developed at Lomonosov Moscow State University by their team as the fully robotic telescopes, that allowed them to solve the problems described above. OAO MO "Optica" has mastered the production of such systems.

This conference is devoted to the 15-th anniversary of MASTER project. It will be a good opportunity to talk about the results achieved by Robotic Observatories in next area: GRBs, SNs, CVs, AGN & BL Lac objects, Gravitational Waves (LIGO/VIRGO) and High Energy Neutrino Follow Up Electromagnetic Observations - ICECube and ANTARES.

eXtreme Matter meets eXtreme Gravity

Workshop Dates: 2017 August 17- 19

Registration: Free, but please take the time to register so that the organizers can get an accurate count of attendees

Deadline for Hotel Booking at Workshop Rate: 2017 July 17

Meeting Location: Bozeman, Montana, USA.

Observations of astrophysical systems where gravity is extreme have the potential to shed light on some of the most profound questions in physics today: from the internal composition of neutron stars to whether Einstein's theory accurately describes the merger of two black holes. Several new instruments have either come on-line recently or will do so in the very near future. For example, in late 2015, aLigo came online and directly detected gravitational waves for the first time in history, while the Neutron Star Interior Composition ExploreR (NICER) will become operational in mid 2017.

The eXtreme Gravity Institute (XGI) at Montana State University will host this workshop to discuss methods for constraining the properties of neutron stars and the dense-matter equation of state. Topics will include:

• Gravitational-wave observations of neutron star binaries and neutron-star/black-hole binaries,
• X-ray observations of millisecond pulsars and other neutron stars
• Theoretical calculations of the dense-matter equation of state,
• Analytical and numerical modeling of neutron star inspirals and mergers.

High Energy Astrophysics Division (HEAD) of the AAS Meeting

Meeting Dates: 2017 August 20 - 24

The Power of X-Ray Spectroscopy (AHEAD Workshop)

Workshop Dates: 2017 September 6 - 8

Abstract Submission & Requests for Travel Grants Deadline: 2017 June 01

Registration Deadline: 2017 June 15

Workshop Location: Warsaw, Poland

The workshop will be a part of the activities of the Integrated Activities for the High Energy Astrophysics Domain (AHEAD) project, funded by the European Commission. The maximum number of participants is 90.

Spectroscopy is a major tool of astrophysics. Then, the X-ray spectroscopy is a major tool of high-energy astrophysics. It can provide us with the temperature, density, velocity and gravitational redshift of the emitting and absorbing plasmas. X-ray spectroscopy still lags behind e.g. the optical spectroscopy in energy resolution, but most spectral lines from highly ionized heavy elements are visible in the X-ray range between 0.1-9.0 keV. This range overlaps with those of the currently working satellites, namely Chandra, XMM-Newton, Astrosat, NuSTAR, Swift, the upcoming missions eROSITA and Athena, and the planned mission Astro-H2. Thus, X-ray observations allow us to study processes taking place in energetic plasmas and not accessible at longer wavelengths. Main types of sources studied by X-ray spectroscopy are clusters of galaxies, supernova remnants, hot stars and their winds, and different types of accreting systems, in particular, active galactic nuclei and binary systems containing compact objects.

The proposed workshop will be devoted to selected aspects of both theoretical and observational X-ray spectroscopy, and, in particular, to the upcoming mission Athena. Athena will provide us with information about the dynamics and distribution of hot matter in the Universe. Thanks to that, we will understand how supermassive black holes grow and how hot gas stabilizes clusters of galaxies. X-rays with energies of 0.1-9.0 keV interact with matter producing emission or absorption from ionized heavy elements. Observations of those lines allow us precisely examine heavy elements content and their chemical evolution. With Athena, we will investigate process of matter falling onto supermassive black hole, in particular its relation with outflowing hot winds (galaxy feedback). Apart from more distant objects, Athena will be suitable to study objects in our Galaxy, such as X-ray binary systems and their outflows, coronae of hot stars, and the Galactic Center.

From Quiescence to Outburst: When Microquasars go Wild

Workshop Dates: 2017 September 25 - 29

Contribution Submission Deadline: 2017 mid-June

Registration Deadline: 2017 July

Workshop Location: Porquerolles Island, France

Unveiling the physical conditions around black holes is one of the major astrophysical challenges of the 21st century. Indeed we are still at the dawn of black hole astrophysics and very little about these objects is understood:

• What are the geometry, dynamics and energetics of the accretion flow onto the black hole?
• How can the accretion of material onto the black hole be simultaneously intimately related to violent relativistic ejecta and/or powerful self-confined persistent jets?
• What are the processes at the origin of the fascinating hysteresis cycles observed in some X ray binaries?

This 5-day workshop (limited to 70 participants to ease discussions) aims at gathering theorists, observers and specialists of the field, discussing the latest results and reviewing the current state of our understanding of the physics of these sources.

Large dedicated time will be devoted to the following specific points:

• Global evolution of XrB in outburst
• Unification CV-BH-NS-ULX-AGN
• Ejections in XRBs (jets and winds)
• Structure and dynamics of accretion flows from temporal approaches
• Instrumental panorama including projects

Transient High Energy Sky and Early Universe Surveyor (THESEUS) Workshop 2017

Workshop Dates: 2017 October 5 - 6

Abstract Submission Deadline: 2017 August 31

Registration Deadline: 2017 September 20

Workshop Location: Naples, Italy

The Transient High Energy Sky and Early Universe Surveyor (THESEUS) is a mission concept under development by a large international collaboration and currently under evaluation by ESA within the selection process for next M5 mission. It is aimed at exploiting Gamma-Ray Bursts for investigating the early Universe and providing a substantial advancement of time-domain and multi-messenger astrophysics. These goals will be achieved through a unique combination of instruments allowing GRB and X-ray transient detection over a broad FOV (more than 1 sr) with 0.5-1 arcmin localization, an energy band extending from several MeVs down to 0.3 keV, and unprecedented sensitivity in the soft X-ray domain, as well as on-board prompt follow-up with a 0.7 m class IR imaging and spectroscopic telescope.

THESEUS is thus perfectly suited not only for addressing the main open issues in cosmology, such as the star formation rate and metallicity evolution of the ISM and IGM up to redshift 10, the signatures of pop III stars, the sources and physics of re-ionization, and the faint end of the galaxy luminosity function, but also for performing an unprecedented monitoring of the X-ray variable sky. It will identify the electromagnetic counterparts to sources of gravitational radiation, which may be routinely detected in the late 2020s/early 2030s by next generation facilities such as aLIGO/aVirgo, eLISA, KAGRA, Einstein Telescope. It will also provide a perfect service and synergy to the next generation of world-class observatories across the electromagnetic and multi-messenger spectrum (e.g., E-ELT, SKA, CTA, ATHENA, IceCube).

Refer to this web site for more information on the THESEUS project.

The aim of this Workshop is to collect the several astrophysical communities involved and interested in the scientific goals, and related technology, of THESEUS, to review the status of the project and further discuss and refine the expected scientific return in the fields of cosmology and astrophysics on which this mission would have an important impact.

The Workshop will consist of both invited/review talks and contributed talks, following these main lines:

• The THESEUS mission design and science objectives
• Probing the Early Universe with GRBs
• Multi-messenger and time domain Astrophysics
• The transient high energy sky
• Synergy with next generation large facilities (E-ELT, SKA, CTA, ATHENA, GW and neutrino detectors)

7th International Fermi Symposium

Meeting Dates: 2017 October 15 - 20

Registration and Abstract Submission Opens: 2017 July

Abstract Submission Deadline: 2017 August 15

Regular Registration Deadline: 2017 September 1

Meeting Location: Garmisch-Partenkirchen, Germany

The two Fermi instruments have been surveying the high-energy sky since August 2008. The Large Area Telescope (LAT) has discovered more than three thousand gamma-ray 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, as well as an excess of gamma-rays from the Galactic center region, both observations have become exciting puzzles for the astrophysics community. 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 full reprocessing of the entire mission dataset with Pass 8 includes improved event reconstruction, a wider energy range, better energy measurements, and significantly increased effective area, all them boosting the discovery potential and the ability to do precision observations with LAT. 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, coordinated observations and analysis techniques. In particular, we also encourage discussion of future prospects/science with Fermi in preparation for the upcoming NASA Senior Review.

International Astronomical Union 2017 Symposium on "Gravitational Wave Astrophysics: Early Results from GW Searches and Electromagnetic Counterparts"

Meeting Dates: 2017 October 16 - 19

Registration: Now Open

Deadline for IAU Travel Grant Applications: 2017 July 7

Abstract Submission Deadline: 2017 September 1 (Abstracts received after Sep 1 will be considered for posters)

Early Bird Registration Deadline: 2017 August 4

Meeting Location: Cape Town, Baton Rouge, Louisiana, USA

This symposium will bring together astrophysicists and gravitational-wave researchers to compare past, present and future of observations of gravitational-wave sources, and share the excitement of a new field in astronomy.

Gravitational waves were predicted 100 years ago by Einstein as part of his general theory of relativity. With the development of new and more sensitive detectors LIGO has now made the first-ever observations of gravitational waves arriving on Earth from space in 2015.

At the time of this symposium in October 2017, the LIGO and Virgo Advanced detectors will have accumulated data from their first two observational runs. The results from these observations will constrain our astrophysical understanding of binary systems of compact objects, rotating or exploding stars and other phenomena. Dozens of our astronomical partners will have followed up gravitational-wave triggers.

This symposium will bring to light the latest results available in gravitational-wave astronomy, progress in multi-messenger astronomy, and the inferences that can be made from joint observations, to open a new window to the cosmos.

Topical Workshop on Dark Matter

Workshop Dates: 2017 November 13 - 15

Deadline for Early Bird Registration: 2017 August 31

Deadline for Guestroom Booking (available on first-come-first-serve basis): 2017 November 1

Deadline for Regular Registration: 2017 November 8

Workshop Location: Singapore

One of the most intriguing problems in present-day physics, astrophysics and cosmology revolves around the nature of dark matter - the dominant form of matter in the universe. Discovered first by pioneers such as Lundmark and Zwicky in the early decades of the last century, the prominence of the dark matter problem has become more acute in recent years. Theoretical and observational evidence agree that dark matter outweighs visible matter by at least five to one, but the identity of dark matter remains a mystery even now.

This workshop will feature the most up-to-date research in this field and introduce various candidates for dark matter. The axion is one such candidate proposed by Nobel Laureate Frank Wilczek, who will be at the workshop in person for discussion. The workshop will also cover the ongoing hunt for dark matter signatures at accelerators and in underground and space experiments, the verification of the existence of dark matter from studies of the cosmic microwave background, and new theoretical ideas about dark matter and dark energy paradigms.

Alsatian Workshop on X-ray Polarimetry

Workshop Dates: 2017 November 13 - 15

Deadline for Registration and Abstract Submission: 2017 August 1 (Note: Maximum of 55 participants)

Workshop Location: Strasbourg, France

50 years after the pioneering experiments, X-ray spectroscopy and timing techniques can be considered as well established. Nonetheless, one prominent feature of X-ray light has not been explored as scrupulously as others: its polarization. Between 1980 and 2000, the instruments were not sensitive enough to go beyond the first X-ray polarimetric results acquired in the 70s but the development of new detection techniques in the early 2000s revived the field. The first X-ray mission to fly a new generation polarimeter will be launched by NASA in 2020; it is now necessary to prepare the ground and begin to refine the theories and simulations needed to exploit the observational results to come.

It is an explicit purpose of this workshop to gather in particular young researchers for two and a half days, to discuss the progress made in X-ray polarimetry, to identify what is still missing and to decide what must be undertaken by 2020. We specifically encourage PhD students and post-docs as well as expert speakers to join the workshop. We aim to facilitate new collaborations that will be ready to exploit the first X-ray polarimetry data to arrive.

Workshop on Astrophysical Opacities

Meeting dates: 2017 August 1 - 4

Registration: Now open

Deadline for Early Registration: 2017 May 31

Deadline for Abstract Submission for Contributed Talks and Posters: 2017 June 30

Deadline for Regular Registration: 2017 July 15

Meeting Location: Kalamazoo, Michigan, USA

The availability of reliable atomic and molecular opacity tables is essential in a wide variety of astronomical models such as the solar and stellar interiors, stellar and planetary atmospheres, stellar evolution, pulsating stars and protoplanetary disks, to name a few. With the advent of powerful observational techniques, e.g. helio and asteroseismology, solar neutrino-flux measurements and exoplanet probes, of 3D hydrodynamic atmospheric simulations that include NLTE and granulation effects, of high-performance atomic and molecular computing and innovative plasma experiments, the accuracy and completeness of the opacity tables are being taken to unprecedented levels.

The Workshop on Astrophysical Opacities (WAO) intends to gather opacity data producers and consumers from both the atomic and molecular sectors in order to contribute to solving outstanding problems and to develop more effective and integrated interfaces. The last time such a workshop took place was at the IBM Venezuela Scientific Center, Caracas, Venezuela, in July 1991. Taken into consideration the success of this first WAO and the huge scientific advancements that have taken place since then in most related research fields, the organizers have been encouraged to organize a second event.
