Diagram of metallicity vs. sSFR for VUDS SFDGs. Different colors represent galaxies with different gas fractions, divided into four bins in f_gas: 0.2–0.4, 0.4–0.6, 0.6–0.8, and 0.8–1. Higher SSFRs also indicate higher gas fractions. Our sample extends the trend of local star-forming galaxies (the blue histogram) toward lower metallicities, showing that the SSFR is anti-correlated with the oxygen abundance, though the dispersion increases at higher sSFR. The overall scatter of the relation is ~0.5 dex in sSFR.
