Fraction of rest-frame NIR flux in substructures (top row) and clumps (bottom row) as a function of the host galaxy’s stellar mass in four redshift bins, each bin spanning 1 Gyr of cosmic history. Galaxies are split in different bins of SFR, as illustrated with the various colored lines. The shaded areas correspond to the 16th and 84th percentiles for each SFR bin. See Fig. 3 for an alternative representation.
