Description:

Title: Do Galaxy Clusters Boil?

Speaker: Mike McCourt, UC Berkeley

Host: Claude-André Faucher-Giguère

Abstract: The hot plasma filling galaxy clusters is susceptible to a convective MHD instability known as the MTI. Understanding the implications of this convection has been surprisingly difficult, however; it depends on both the large-scale evolution of the cluster and on the plasma physics of the gas. I will describe a new set of "semi-cosmological" simulations which capture enough of the cosmic evolution of galaxy clusters to reproduce their large-scale properties but still provide an idealized environment in which to study cluster convection and its implications. I will also describe some future applications of these simulations to other problems in galaxy formation.
