Dependence of different properties of baryons on the stellar mass. Top panels: Fraction of baryons (left) and cold gas (right) within $r_{\mathrm{hm}}^{★}$. Bottom panels: Density-weighted mean gas temperature (left) and mean density (right) within $r_{\mathrm{hm}}^{★}$. The grey shades represent the density of galaxies in the plane defined by stellar mass and the corresponding property, computed from the data using a Gaussian smoothing kernel (normalization is different for each panel). Colour contours enclose 80% of the systems in different SSs (SS1: red, SS2: yellow, SS3: green, SS4: blue). The dashed and dash-dotted vertical lines mark $M_{\mathrm{on}}^{★}$ and $M_{\mathrm{off}}^{★}$, respectively, whereas the dotted horizontal line represent the density threshold for star formation.
