Cosmic Rays and Thermal Instability in the Circumgalactic Medium

Cool gas in the circumgalactic medium (CGM) drives galaxy evolution by fueling star formation. One explanation for the observed abundance of cool gas is that it precipitates directly out of the hot CGM gas through the thermal instability. Using idealized simulations of thermal instability in a gravitationally stratified plasma, I will present the impact of cosmic rays on the predicted abundance and density profiles of cool CGM gas.
