Specific star formation rate (sSFR)–mass relation for galaxies in the low-density field (left panel), and galaxies in the high-density field and cluster virial and outer regions (green dots, orange diamonds, and black stars in the central panel). The vertical and horizontal lines show the stellar mass limit and our adopted separation between star-forming and passive galaxies. The blue dashed line is the fit to the relation of the sample including all the environments. The right panel shows the distribution of the differences between the galaxy sSFRs and their expected values according to the fit giventheir mass.
