Galaxy ﹩{M}_{\mathrm{mol}\mathrm{gas}}﹩–SFR relation, that is, star formation law. Data points are color coded by galaxies’ offsets from the ﹩{M}_{\star }﹩–SFR MS (﹩{\rm{\Delta }}\mathrm{MS};﹩ using Speagle et al. 2014 MS). Solid circles are A³COSMOS galaxies, and crosses represent all other galaxies from the complementary samples. The blue and red lines represent, respectively, the star formation laws from Sargent et al. (2014) for normal star-forming galaxies and extreme starbursts with a factor of ∼15 offset. See discussion in Section 4.4.
