Gravitational pressure of gas disks as a function of the physical-scale radius for central galaxies from GAEA at z ∼ 0.5 (left) and z ∼ 1 (right). The solid lines represent median values while the shadows show the 16th and 84th percentiles. Different colors represent different stellar mass bins as labeled. Solid vertical lines are the effective radii of cold gas disks for GAEA galaxies. The dashed lines show the corresponding measurements for TNG galaxies using two different methods (more details in the text).
