Median radial profiles of physical quantities of 30 random galaxies (10 random galaxies for each size class) that end up as centrals at different epochs: radial velocity of the gas (first row), gas specific angular momentum normalized by the radius (second row), gas density times r² (third row), sSFR (fourth row), and stellar density times r² (fifth row). The r values have been converted to physical kiloparsecs. The colors are the same as in Fig. 3. The pink shaded regions indicate the redshift-dependent, poorly resolved radii and the dashed vertical lines indicate the redshift-dependent stellar half-mass radius.
