Gas temperature as a function of total gas density in our fiducial CHEM_MHD model at t = 196 Myr. Blue and red indicate the regions at R > 0.5 kpc and R < 0.5 kpc, respectively. Contours contain [99, 95. medium with a cold (T = 10² K) and warm (T = 10⁴ K) phase. The hot phase (T = 10⁶ K) is absent since our simulations do not include stellar feedback or other processes that can create it.
