Accretion timescales Mcs/ Ṁacc = 0.1, 1, 5, and 10 Myr are indicated from top to bottom with the dashed lines. The original data for the clouds and the galaxies in Fig. 2 (green and red open circles) are shifted −1.3 dex in the x-axis (green and red filled circles), corresponding to a fraction of gas directly associated with star formation of 5% the total dense gas mass measured in those systems.
