Cosmic ray streaming in galaxies and galaxy clusters

Joshua Wiener (UCSB) - December 8, 2014 at 12:10 pm

Cosmic rays comprise a significant amount of energy in galaxy clusters, and are as energetically important as the thermal gas and magnetic field in the Milky Way. A careful treatment of cosmic ray transport is necessary to predict dynamics (such as CR driven winds) based on the radio observations which indicate their abundance. In this talk I will discuss how cosmic rays travel through and couple energetically with magnetized plasma, focusing specifically on the effects of free streaming in cluster and galactic environments.

The seminar will be held in 131A Campbell Hall.
