Fig. 6

Left: correlation between ⟨log age⟩L at 1 HLR and the galaxy-averaged age . Black dashed line shows the fit, which is almost equal to the one-to-one line. Black dots mark spheroidal galaxies, C ≥ 2.8. Red and blue plus signs establish the relation between the nuclear (inner 0.1 HLR) and outer disk (2 HLR) ages as a function of
. Center: correlation between the stellar mass surface density at 1 HLR (gray circles) and
. Black dashed line shows the fit to all the points, and dashed blue line the fit to the disk galaxies; plus signs like in the left plot. Right: correlation between the galaxy-averaged stellar mass surface density and galaxy stellar mass. Black points are spheroidal galaxies, C ≥ 2.8. The dashed lines show the fits, for disk (blue) dominated galaxies and spheroidals (red). Black dashed line is the fit to all the galaxies.
