High-throughput X-ray Astronomy in the eXTP Era

Meeting Dates: 2017 February 6 - 8
Deadline for Registration and Abstract Submission: 2016 December 12
Meeting Location: Rome, Italy

eXTP (enhanced X-ray Timing and Polarimetry) is an ambitious high-throughput X-ray astronomy mission concept being studied by a large consortium of Chinese and European scientific institutions, led by the Institute of High Energy Physics of the Chinese Academy of Sciences for a launch before 2025 on a Chinese platform. The core science of eXTP aims at studying matter under the extreme conditions of density (equation of state and QCD), gravity (strong field gravity and GR) and magnetism (strong and extreme magnetic fields and QED).Primary targets include isolated and binary neutron stars, strong magnetic field systems like magnetars, and stellar-mass and supermassive black holes.

The mission carries a unique and unprecedented suite of state-of-the-art scientific instruments enabling for the first time ever the simultaneous spectral-timing-polarimetry studies of cosmic sources in the energy range from 0.5-30 keV (and beyond).

The eXTP consortium is proud to invite the science community at large to take part to the First Science Meeting dedicated to the high-throughput X-ray Astronomy and the eXTP mission. The goal of the meeting is to shape the directions of the research in the field of combined X-ray timing, spectroscopy, and polarimetry, collecting contributions to shape the scientific goals of eXTP.

More details about the eXTP mission may be found here and in the scientific payload paper.

Conference on Cosmology, Gravitational Waves and Particles

Meeting Dates: 2017 February 6 - 10
Deadline for Early Registration: 2016 November 30
Deadline for Regular Registration: 2017 January 20
Meeting Location: Singapore

On February 2016, physicists announced the discovery of gravitational waves, which were predicted in 1916 by Albert Einstein in his theory of General Relativity. About 1.3 billion years ago, two giant black holes collided and formed one very big black hole. During this collision strong gravitational waves were emitted. They were discovered at the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States. Experts from the detectors will present their results at the conference. Theoreticians will discuss the implications of the discovery. There will also be lectures on the expansion of the universe, on cosmology, on astrophysics and on particle physics.

IAU Symposium 331: SN 1987A, 30 years Later - Cosmic Rays and Nuclei from Supernovae and Their Aftermaths

Meeting Dates: 2017 February 20 - 24
Meeting Location: Saint-Gilles, La Réunion Island (France)

On the occasion of the 30th anniversary of SN 1987A, this Symposium will explore the link between the stellar progenitors and the multi-wavelength/multi-messenger manifestation of core-collapse Supernovae (cc-SNe) and their remnants (SNRs) in terms of extreme sources of high-energy particles and nuclei. By bringing together theorists, observers and instrumentalists from diverse geographical regions and fields of expertise, focussing on the best studied case, the Symposium, through an interdisciplinary approach, will span a broad spectrum of important, interconnected topics within this rapidly evolving research field of cc-SNe and SNRs.

The organizers invite contributions on the following topics:

Latest evolutionary stages of massive stars as cc-SN progenitors;
cc-SNe as stellar explosive outcomes;
cc-SN explosion mechanisms;
cc-SN remnants and impacts;
Particle acceleration & origin of cosmic rays;
SN 1987A, 30 years later;
Non-thermal multi-wavelength/multi-messenger data on SNe and SNRs.

Quasars at All Cosmic Epochs

Meeting Dates; 2017 April 2 - 7
Registration Opens: 2016 early November
Deadline for Registration and Payment: 2017 January 31
Meeting Location: Padova, Italy

Quasars were discovered slightly more than 50 years ago. All the improvement in telescope light gathering and in computing power notwithstanding, we are still missing a clear connection between observational properties and theory for quasars, as provided, for example, by the H-R diagram for stars. We do not yet have a complete self-consistent view of nuclear activity with predictive power, as we do for main-sequence stellar sources. At the same time quasars offer many "windows open onto the unknown". On small scales, quasar properties depend on phenomena very close to the black hole event horizon. On large scales, quasars may effect evolution of host galaxies and their circum-galactic environments. The potential of quasars to map the matter density of the Universe and help reconstruct the Universe's spacetime geometry is still largely unexploited.

The time is ripe for a critical assessment of our present knowledge of quasars as accreting black holes and of their evolution across the cosmic time. The aim of this meeting is to review and contextualize the main observational scenarios following an empirical approach, to present and discuss the accretion scenario, and then to analyze how a closer connection between theory and observation can be achieved, identifying those aspects of our understanding that are still on a shaky terrain and are therefore uncertain knowledge.

The meeting will cover topics ranging from the nearest environment of the black hole, to the environment of the host galaxies of active nuclei, and to the quasars as markers of the large scale structure and of the geometry of spacetime of the Universe. Systematic attention will be devoted to some key problems that remain outstanding and are clearly not yet solved: the existence of two quasar classes, radio quiet and radio loud, and in general, the systematic contextualization of quasar properties, the properties of the central black hole, the dynamics of the accretion flow in the inner parsecs and the origin of the accretion matter, the quasars' small and large scale environment, feedback processes produced by the black hole into the host galaxy, quasar evolutionary patterns from seed black holes to the present-day Universe, and the use of quasars as cosmological standard candles.

Key Topics

1. Observational properties of quasars as luminous active galactic nuclei 
2. Accretion processes on supermassive black holes
3. Contextualization and connection between theory and observation for the emitting region of quasars
4. Quasar evolution over cosmic time and quasars as cosmological tools
5. Feedback and environment of active galaxies and quasars

29th Texas Symposium on Relativistic Astrophysics

Meeting Dates: 2017 December 3 - 8
Registration and Abstract Submission Open: 2017 April 14
Abstract Submission Deadline: 2017 August 25
Regular Registration and Hotel Deadline: 2017 October 20
Late Registration Deadline: 2017 November 24
Meeting Location: Cape Town, South Africa

The series of Texas Symposia on Relativistic Astrophysics began in 1963 and they are normally held every two years. Major astrophysical discoveries have been announced and discussed in the field related to relativistic theory of gravitation and cosmology, such as black-holes, quasars, neutron stars, X-ray binaries, gamma-ray bursts, particle acceleration, the cosmic background, dark matter and dark energy. The 29th Symposium will be the first ever to be held on the African continent, emphasizing Southern Africa's role as the host of world-leading astrophysical facilities, such as the Southern African Large Telescope, the High Energy Stereoscopic System (HESS), and the future Square Kilometre Array.

The organizers are excited to welcome hundreds of international astrophysicists and physicists to Cape Town, to review remarkable discoveries and prospects, such as the breakthrough detection of gravitational waves by the LIGO/VIRGO collaboration. The symposium also marks the 100th anniversary of the postulation of the cosmological constant ("Einstein's Biggest Blunder"). The Symposium will include morning plenary sessions and afternoon parallel sessions which will function as mini-symposia in each sub-field. The plenary sessions will consist of 30-45 min review talks. The afternoon sessions will feature oral (about 20 min) and poster contributions.

Other Selected Astronomy, Physics and Space Science meetings

On the Origin (and Evolution) Of Baryonic Galaxy Halos

Meeting Dates: 2017 March 13 - 17
Abstract Deadline for Talks and Posters: 2016 August 27
Registration Fee Deadline: 2016 December 1
Meeting Location: Galapagos Island, Ecuador

This meeting will focus on the baryonic content of galaxy halos -- their properties, origin and evolution with cosmic time.

The halos of our own Milky Way galaxy and our close neighbour M31 have been studied in some detail. Deep, wide and detailed observations of galaxy halos beyond the Local Group are becoming more ubiquitous. Simulations, that incorporate realistic baryonic physics in a cosmological context have also made significant progress in recent years in modelling galaxy halos. These simulations predict outer halo regions that differ strongly in their formation processes and properties from the well-studied inner regions of galaxies. Halos have long dynamical times and as such preserve the unique signatures of galaxy assembly. This meeting will bring together observers and simulators of the baryonic halos of galaxies, focusing on extragalactic halos.

Topics of focus include:

* the origin and evolution of baryonic halos

* how to define the stellar halo of an elliptical galaxy

* the stellar components of galaxy halos: metallicity, age, kinematics, density

* substructures in galaxy halos

* in-situ vs ex-situ formed stars

* halo tracers, such as resolved stars, globular clusters, planetary nebulae, satellite galaxies and diffuse gas

Detecting the Unexpected: Discovery in the Era of Astronomically Big Data

Meeting dates: 2017 February 27 - March 02
Pre-Registration: Now available
Pre-Registration Closes: 2016 November 01
Deadline for Registration: 2017 January 06
Meeting Location: Baltimore, Maryland, USA

What tools do astronomers need to discover new classes of objects and complex trends in data sets too large to inspect by eye? This STScI workshop will explore this question in specific astronomical contexts and a with a range of tools. How can we find new events in the time domain, and make smart choices about follow-up in real time with limited resources? How can we find new features of our Galaxy in rich databases with more than spatial and kinematic information? What are the prospects for tools to explore the spectroscopic data sets of the present and future? We will focus on three kinds of discovery tools during the workshop: citizen science, machine learning, and data-integrated visualization.

This will be a unorthodox, hands-on workshop. Attendees are invited to provide exploration tools and data sets in advance of the workshop, which will be integrated into a computing environment provided to all participants. We will have hands-on sessions where discovery tools are taught by experts. There will be "unconference" sessions during which attendees can propose their own discussion topics in break-out rooms. There will also be a full day "hack", for attendees to experiment with the presented tools on STScI and contributed data sets and build their own tools.

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.
