Phase structure of the galactic outflows in both the CRMHD (left) and MHD (right) simulations. We show the probability distribution function of the volume-weighted mass flux ρvz to highlight gas that is responsible for the mass loss from the galaxy. The top panels show the sound speed (which can also be seen as a proxy for the gas temperature) of gas inside R<30 kpc and 3 kpc<|z|<100 kpc while the bottom panels show the hydrogen number density over outflow velocity vz. We mark the Mach numbers 0.1, 1, and 10 which can be used to infer that the outflow in both simulations is supersonic. The contour in each panel encloses 75% of the total mass flux. The phase structure of the CRMHD is more diverse and spans multiple orders of magnitude in density while being cooler than the MHD simulation.
