Median evolution of the half-mass radii (top) and total masses (bottom) of the Normals (orange), Compacts_MB (blue), and Compacts_SB (green) for galaxies that end up as centrals at z = 0. The solid, dashed, and dotted lines represent the stellar, gas, and DM components, respectively, and all quantities are measured over the entire subhalos. The lines are the medians, and are only shown when we have at least five galaxies at that epoch; the shaded region shows the uncertainty on the median, estimated using bootstraps.
