M_gas versus redshift for our GOODS-ALMA 2.0 galaxy sample. Filled symbols represent galaxies with a Herschel counterpart and open symbols galaxies without a Herschel counterpart. The black line indicates the M_gas completeness limit as a function of redshift (solid and dashed for MS and SB templates, respectively). This limit correspond to the GOODS-ALMA 2.0 ∼100% completeness, associated with flux densities S_1.1 mm > 1 mJy for sources with dust continuum sizes up to 1″ FWHM (see Gómez-Guijarro et al. 2022) for the median metallicity of our galaxy sample.
