Gallery of the plasma beta parameter β_P at z = 0 for the same sixteen TNG-Cluster halos and the same setup as in Fig. 1. Each panel shows the central region and extends 0.2r_500c from side-to-side, while the white circles indicate 0.1r_500c. As the panels are ordered by ascending central entropy K₀, we also see that in some of the SCCs the decrease of β_P toward the core is amply visible. We also find lower beta for more massive clusters, in agreement with Marinacci et al. (2018).
