ICM physics and modeling

June 15-17, 2015

Max-Planck Institute for Astrophysics, Garching, Germany

Being the diffuse medium in the largest virialized structures in the Universe, intracluster medium (ICM) is a unique laboratory for physics ranging from the largest scales in our Universe down to the scale of particle interactions. On the scale of galaxy clusters, gravity is the dominating force which leads to nearly universal thermodynamical profiles of the ICM and enables galaxy clusters to be a useful probe for cosmology. At the same time, ICM exhibits rich phenomena at all scales such as turbulence, magnetic-fields, cosmic rays, radio halos, radio relics, cold fronts, cool cores, and energy injection from black holes. To understand them fully we may need to treat the ICM in its full complexity, as a magnetized, weakly collisional plasma.

What is our current understanding of the astrophysical processes in the ICM, and what are the possible missing pieces? What is the impact of these astrophysical processes on the global hot X-ray emitting ICM and the cluster mass estimates? Can we tackle this multi-scale problem with physically motivated sub-grid models? Do we understand microphysics of the ICM well enough for making robust predictions? What clues can we gain from the new observations? This workshop aims to bring together a number of astrophysicists who share the close interest on these questions to exchange knowledge and ideas via discussions and talks, and to facilitate collaborations among the participants. Here is a list of sessions and major topics.
