dc.description.abstractWe present the calibration between the dust continuum luminosity and interstellar gas content obtained from the Valparaíso ALMA Line Emission Survey (VALES) sample of 67 main-sequence star-forming galaxies at 0.02 < z < 0.35. We use CO(1–0) observations from the Atacama Large Millimetre/submillimetre Array to trace the molecular gas mass, MH2, and estimate the rest-frame monochromatic luminosity at 850 μm, Lν850, by extrapolating the dust continuum from magphys modelling of the far-ultraviolet to submillimetre spectral energy distribution sampled by the Galaxy And Mass Assembly survey. Adopting αCO = 6.5 (K km s−1 pc2)−1, the average ratio of Lν850/MH2 = (6.4 ± 1.4)× 1019 erg s−1 Hz−1 M−1⊙, in excellent agreement with literature values. We obtain a linear fit of log10(MH2/M⊙)=(0.92±0.02)log10(Lν850/ergs−1Hz−1)−(17.31±0.59). We provide relations between Lν850, MH2 and MISM when combining the VALES and literature samples, and adopting a Galactic αCO value.
