At a given M, QGs with a higher Σ1 are older. We plot Σ1 vs. M for QGs, color coded by the three mass-weighted age bins of Figure 3. Galaxies above the Σ1 ridgeline, indicated with the black line, are older than similar-mass galaxies below this line. The inset shows the distribution of distances from the Σ1 ridgeline for the three age categories.
