Co-Evolution of Cosmic Rays and Thermal Plasma in Galaxy Clusters

Not scheduled
25m

Speaker

Ellen Zweibel (U Wisconsin-Madison)

Description

Macroscale magnetized turbulence, acting jointly with microscale kinetic turbulence, can heat weakly collisional, high beta plasmas such as the ICM through a process known as magnetic pumping. This talk, which is complementary to a presentation by Francisco Ley, will discuss two effects and their relevance to energy balance in the ICM: enhancement of the heating rate in the presence of mesoscale turbulence, and extraction of a nonthermal tail that can form a seed population of cosmic rays.
