Visual impression of a subset of gas quantities around a Milky Way-mass halo in the fiducial TNG (upper panels), TNG-CR (center panels), and TNG-CR-NF (lower panels) runs, cross-matched across the various realizations. Images extend ±R_200c in all cases, along the plane and in the perpendicular direction, and scale bars correspond to a 100 kpc. From left to right, we show temperature, density, ratio of P_CR to P_mag, and ratio of P_non, th(= P_CR + P_mag) to P_th. While profiles of temperature are largely similar across the three runs, the density of gas is lower in the TNG-CR-NF run, particularly in the halo. In the two CR runs, P_CR dominates over P_mag in all regions except the central disk, where the two are in rough equipartition. In all three runs, only the central region of the halo is dominated by nonthermal pressure support. The fraction of nonthermal pressure in outer regions of the halo is relatively higher in the CR runs than in Fid. TNG, however.
