Overview of sub-samples used in this work.

sub-sample name	selection criterion
low-SFR	20% lowest star formation rate (SFR)
passive	20% passive galaxies / lowest specific SFR (sSFR)
red	20% reddest galaxies / highest (g-i)
low-Z_cold	20% lowest cold gas-phase metallicities (Z_cold) and (g-i) > 2.35
high-Z_cold	20% highest cold gas-phase metallicities (Zcold) and (g-i) > 2.35
(i)	(ii)

Notes. This table compiles our choice of sub-samples extracted from the modelled SAM-CMASS mock galaxy catalogue, Gal-dens, at z_ref = 0.56 – the redshift of sample selection. In column (i), we state the sub-sample’s name which is inspired by its selection criterion shown in column (ii).
