Mass–size distribution for our LIRGs including ETGs and local spiral galaxies (i.e., MS SFGs; Leroy et al. 2021). ETGs are marked with (blue contour) down-pointing triangles and MS SFGs with up-pointing orange triangles. LIRGs are identified following the color code used in previous figures. The blue and red slopes represent the mass–size relations derived by Shen et al. (2003) (see also Fernández Lorenzo et al. 2013) for late- and early-type local galaxies, respectively.
