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.

AHEAD High Resolution X-ray Spectroscopy School

School Dates: 2017 November 14 - 17
Registration: Now Open (and free of charge)
School Location: Alicante, Spain

High resolution spectroscopy is a fundamental tool in X-ray astrophysics. It provides unique plasma diagnostics in a variety of astrophysical contexts from clusters of galaxies to solar system bodies. Current grating-based spectrometers (XMM-RGS, Chandra HETG) provide the highest spectral resolution achievable nowadays. The calorimeters (XARM, Athena) will increase the resolution to unprecedented levels opening a new era of X-ray astrophysics that will expand our knowledge of the high energy universe.

AHEAD (Integrated Activities for the High Energy Astrophysics Domain) aims at providing young astronomers the specific theoretical and practical skills to successfully exploit the current and future generation of X-ray instruments. To this end, world class experts in several fields will deliver lectures and conduct hands on sessions, including analysis of real calorimeter data. The students will have the opportunity to interact with renowned scientists in a highly motivating environment. This achool is for students and postdocs. Although the course will be self-contained, previous background in X-ray astronomy (not necessarily high spectral resolution) is highly recommended. The School is limited to 40 students.

IAU Symposium 342: Perseus in Sicily: From Black Hole to Cluster Outskirts

Meeting Dates: 2018 May 14 - 18
Registration and Abstract Submission: Available in mid-September
Meeting Location: Noto, Sicily, Italy

The Perseus cluster has recently been the stage of some ground-breaking discoveries:

on ultra-fine linear scales, space-VLBI has revealed fundamental details of the jet launching mechanism,

on large scales, and at superb energy resolution, Hitomi has revealed surprising details about the gas dynamics, shaking our current understanding of the cool core phenomenon,

in gamma rays of high and very high energy, dramatic activity with extremely short time scales has been reported both in NGC 1275 and IC 310.

The importance and timeliness of discussing these and other topics, including feedback, is enhanced by the many developments recently achieved also in the fields of theory of accretion and particle acceleration, as well as to the great improvement in performance and accuracy of numerical simulations and imaging techniques.

The organizers will gather multi-wavelength observers and theoreticians, experts from the event horizon out to the Megaparsec scales, encouraging interactions and discussion. Participation of qualified scientists with limited means of support, e.g., colleagues from economically less privileged countries and young scientists, will be facilitated thanks to IAU Travel Grants.

Key topics will include:

- approaching the Schwarzschild radius: methods to measure BH mass and spin

- BH magnetosphere & sphere of gravitational influence

- hot vs cold accretion

- magneto-hydrodynamical processes in disks and jets

- jet production, collimation, and acceleration mechanisms

- HE emission: site and mechanisms, particle acceleration, leptonic vs hadronic processes

- jet-medium interaction on galactic and cluster scales

- thermal and non-thermal emission in galaxy clusters

- turbulence, gas heating and cooling

- AGN winds and BH-galaxy coevolution

Time-Domain Astronomy: A High Energy View (XMM Newton Science Workshop 2018)

Workshop Dates: 2018 June 13 - 15
Registration Opening and Abstract Submission: 2018 January
Meeting Location: Villafranca del Castillo, Madrid, Spain

Many astronomical objects are time variable. Time variability encodes key information about the source physics; this information is complementary to that in energy spectra and is essential for our complete understanding of the phenomena involved. Most X-ray emitting objects show variability whose timescales can span many orders of magnitudes, from decades down to milliseconds depending on the source. Studying X-ray variability, we can probe the physics of a large number of phenomena in a plethora of different astrophysical objects, from large scale changes of galactic environments down to the direct environment of compact accretion objects. Objects studied include solar system objects and stars, novae and supernovae, pulsars and magnetars, Galactic black holes and supermassive black holes in the centre of active galactic nuclei.

With the upcoming multi-wavelength time-domain monitoring facilities such as Gaia, LSST, ASAS, TESS, PanSTARRS in the optical band, or SKA in the radio band, to name a few, an enormous potential for multi-wavelength studies will soon be available. The workshop aims to summarise the current understanding of the variability in high energy astrophysical objects in order to explore the potential synergy with other (new) time-domain facilities and to foster cooperation between observers in different energy bands.

Registration opening and abstract submission are planned for January 2018.

The time has come to synthesize new knowledge from the incredibly rich trove of data, models, and theories on HMXBs accumulated over the last 50 years. The Symposium will bring together a broad range of scientists with the aim to share their insights and further advance our understanding of HMXBs. New powerful synergetic approaches will be developed and put in a broad astrophysical context during the XXX IAU General Assembly. The Symposium will build a bridge between mature field of massive binary astrophysics and nascent field of gravitational wave astronomy. This large international meeting will consolidate our knowledge on massive stars, binary evolution, accretion physics, compact objects and gravitational wave sources to give us a new perspective on the cosmos illuminated by HMXBs.

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.
