Correlation between the inner gradient (calculated between the galaxy nucleus and at HLR) of log μ_∗ (upper panel) and ages (bottom panel) and galaxy stellar mass. Black and gray points are galaxies with concentration index above (early-type galaxies) and below (late-type galaxies) 2.8, respectively. Median gradient value for different mass bins (log M_∗ (M_⊙) = 9.2−10.2, 10.2−10.6, 10.6−10.8, 10.8−11.0, 11.0−11.2, 11.2−11.4, 11.4−11.6, and 11.6−12.0) for early-type galaxies (dots) and late-type galaxies (stars) are shown. Stars and large colored dots are located at the mean value of log M_∗ of the galaxies that belong to the corresponding mass bin.
