Environmental dependence of the gas-phase mass–metallicity relation.
| Environmental | Range of | Δ(log Zgas/Z⊙) |
|---|---|---|
| diagnostic | log(M⋆/M⊙) | |
| Local density δ | 9.3−9.9 | −0.07 ± 0.06 |
| Overdensity structures | 9.3−9.9 | −0.10 ± 0.05 |
Notes. Gas-phase MZR as a function of local galaxy density (higher or lower than the median sample) and overdensity flag. We highlight in Col. 3 the difference in metallicity Δ(log Zgas/Z⊙) between galaxies in overdensities and in the field in each stellar mass bin, for which we give the corresponding range in Col. 2.
