Fig. 9.
Top panel: molecular KS relation: H2 surface density (from dust-based gas mass minus atomic mass) vs. star formation rate surface density (from total integrated LTIR) for LARS compared to COLDGASS (blue) and a sample of z ∼ 1−3 star-forming galaxies from Genzel et al. (2010) (grey open squares). Bottom panel: KS relation: total gas surface density (dust-based) vs. star formation rate surface density (from total integrated LTIR). The COLDGASS galaxies (blue) and Kennicutt (1998) samples of local spirals (grey filled circles) and ultra-luminous infrared galaxies (grey filled triangles) are shown as reference. Black diagonal lines indicate (from top to bottom) constant gas depletion times of 0.1, 1 and 10 Gyr.
