Left panel: Radial entropy profiles for the combined sample extracted from the MACSIS and BAHAMAS simulations (Barnes et al. 2017) compared with the one derived from our model for M₅₀₀ = 2.5 × 10¹⁴ M_⊙ and with the observed REXCESS profile. Right panel: Radial entropy profiles from the FLAMINGO simulation for objects in the M₅₀₀ = 10¹⁴ − 10^14.5 M_⊙ mass bin compared with the one derived from our model for M₅₀₀ = 2.5 × 10¹⁴ M_⊙ and with the observed REXCESS profile.
