NRAO Colloquium

Date: Fri. 10 Apr, 2015 11:00 am - 12:00 pm
Duration: 1 Hour
Location: NRAO

Dr. Maxim Markevitc of the Joint Space-Science Institute, will be the guest speaker for the NM-NRAO Colloquium. He will present "Physics of Intracluster Medium from High Angular Resolution X-ray Studies." Mergers of galaxy clusters produce disturbances in hot intracluster medium, such as shocks and cold fronts, that can be used as tools to study the physics of galaxy clusters. X-ray observations of shock fronts provide information on the shock Mach number and velocity. Combined with radio data, these observations shed light on the production of ultra-relativistic particles that are known to coexist with the cluster thermal plasma. Only a few unambiguous shock fronts have been seen in X-rays so far, and almost all of them have a coincident diffuse radio feature. This talk will summarize the current X-ray observations of cluster mergers, as well as some recent radio data and high-resolution hydrodynamic simulations. 11 a.m. in the auditorium of the Domenici Science Operations Center (NRAO).
