PHANGS–ALMA on the star-forming main sequence and size–mass relation. PHANGS–ALMA targets in SFR–M and ReM space. PHANGS–ALMA targets appear as red hexagons. For comparison, galaxies observed as part of the xCOLD GASS survey are represented by blue squares (Saintonge et al. 2017). We show a large sample of local galaxies as gray dots. In the SFR–M space these are all galaxies with d < 50 Mpc and measurements from Leroy et al. (2019). In the lower panel, we combined masses from Leroy et al. (2019) with sizes from Muñoz-Mateos et al. (2015), with the latter being the limiting quantity. Black lines show scaling relations relevant to late-type galaxies. In the top panel we show the star-forming main sequence as a solid black line, with the specific formula from Leroy et al. (2019). In the bottom panel we show the r-band result for late-type galaxies from Lange et al. (2015). We show the distribution of offsets from both relations in Figure 17.
