Cosmic Ray Mediated Thermal Fronts in the Warm-hot Circumgalactic Medium

We investigate the 1D plane-parallel front connecting the warm (10 ^4 K) and hot (10 ^6 K) phases of the circumgalactic medium (CGM), focusing on the influence of cosmic rays (CRs) in shaping these transition layers. We find that cosmic rays dictate the thermal balance while other fluxes (thermal co...
