Magnetic field and CRp-to-thermal energy properties of the baseline cluster model. Left: magnetic field profile obtained by assuming a fixed magnetic field strength of 5 μG at 100 kpc, and a scaling relative to the thermal density as . Right: CRp-to-thermal energy profile for different models of the CRp distribution. The color lines show each real cluster, using the same colors as in the left panel, and with n_CRp ∝ n_gas. The black lines correspond to variation in the CRp scaling with respect to the thermal gas for the baseline cluster model, as indicated in the legend.
