Projections of the hydrogen column density, NH, employing purely advective CR transport. The panels show the xz plane of a section extending from z=0 to z=2H and the depth of the projection is 1 H. The snapshot is at t=7 tcool≈2 tff. All simulations were initialised with different relative CR pressure, Xcr, 0. The density of the clouds decreases with increasing CR pressure, while the cloud size increases. In the CR pressure dominated run with Xcr, 0=3, cold gas condensation is entirely suppressed. This illustrates that advective CRs alter the morphology of the CGM significantly and suppress the formation of cold clouds.
