Comparison of spherically averaged radial profiles of the CR pressure (P_cr = e_cr/3) between TNG-CR and an advanced spectral CR scheme (Girichidis et al. 2024). Solid, dashed and dotted curves correspond to M_200c ∼ 10¹², 10¹¹ and 10¹⁰ M_⊙ halos, respectively. In the Girichidis et al. (2024) simulations, the galaxies at the center of these halos have stellar masses M_⋆ ∼ 10^10.5, 10^9.5 and 10^8.5 M_⊙, shown through the different black curves. Red curves correspond to TNG-CR profiles of galaxies matched with respect to stellar mass, while profiles of the halo-matched TNG-CR sample is shown in orange. Only for the solid red curve, we additionally plot the 16th–84th variation across the sample. The stellar mass matched sample, except for the least massive bin, roughly matches the black curves (within a factor of ∼1.5). The halo mass matched sample however is offset by much larger factors, owing to suppressed stellar masses at fixed halo mass.
