Evolution of the growth rate in number density (top panel) as a function of redshift for red galaxies ( = 1) in different mass ranges (represented by different symbols and colours). Values have been plotted at the intermediate redshift between two adjacent redshift bins. In the bottom panel, we show the evolution with redshift of the fraction of blue galaxies ( = 2−4) that are transforming into red galaxies per Gyr (see text). In all the panels, hatched regions refer to GSMFs that are complete in the mass range and redshift considered, while dotted lines are connecting points at redshifts where the GSMF is not complete in the considered mass range.
