724 galaxies from the final sample shown in the SFR–M_* plot (left). Blue points represent the SFGs, red points show the location of the quiescent galaxies, and grey points the AGNs classified as described in Sect. 3.2. Right panel displays the same plot showing star-forming and quiescent galaxies color-coded by the f_0.25 μm parameter. The solid black line represents the MS from Aird et al. (2017) at redshift 0.15 (the mean redshift of our sample of normal galaxies). The dashed line shows the threshold 1.3 dex above and below the MS.
