Notes. Column (1): Parameters considered in the comparison; Col. (2): (Median) size of the different tracers as well as the (median) stellar mass of our LIRG sample; Cols. (3–9): Scaling factors derived when comparing the size of the different tracers and stellar mass of low- (Cols. 3–6) and high-z (Cols. 7–9) samples with those derived for our LIRGs. The samples involved in the comparison are: spiral galaxies from the EDGE-CALIFA (Col. 3) and PHANGS-ALMA samples (Col. 4), ETGs (Col. 5), local ULIRGs (Col. 6), high-z SMGs (Col. 7), high-z SFGs (Col. 8) and high-z compact SFGs (Col. 9; see text for details).
