Redshift evolution of the mean molecular gas fraction and molecular gas depletion time of MS galaxies, with the M_gas from the H17_{αCO = 4.35} gas mass calibration. Dots show the mean molecular gas fraction and molecular gas depletion time from our work. Stars represent the local reference taken from Saintonge et al. (2017). Solid lines display the analytical evolution of the molecular gas fraction and molecular gas depletion time inferred with the H17_{αCO = 4.35} gas mass calibration. Dashed lines show the analytical evolution of the molecular gas fraction and molecular gas depletion time inferred with the H17 gas mass calibration (used throughout the paper). Symbols and lines are color-coded by stellar mass.
