Gas-phase mass-metallicity relation for LEGA-C gal.
Listed in IVOA Registry (Virtual Observatory)
The massive end of the gas-phase mass-metallicity relation (MZR) is a sensitive probe of active galactic nuclei (AGN) feedback that is a crucial but highly uncertain component of galaxy evolution models.
Description
In this paper, we extend the z~0.7 MZR by ~0.5dex up to log(M*/M_{sun}_)~11.1. We use extremely deep VLT VIMOS spectra from the Large Early Galaxy Astrophysics Census (LEGA-C) survey to measure metallicities for 145 galaxies.
The LEGA-C MZR matches the normalization of the z~0.8 DEEP2 MZR where they overlap, so we combine the two to create an MZR spanning from 9.3 to 11.1 log(M*/M_{sun}_). The LEGA-C+DEEP2 MZR at z~0.7 is offset to slightly lower metallicities (0.05-0.13 dex) than the z~0 MZR, but it otherwise mirrors the established power-law rise at low/intermediate stellar masses and asymptotic flattening at high stellar masses. We compare the LEGA-C+DEEP2 MZR to the MZR from two cosmological simulations (IllustrisTNG and SIMBA), which predict qualitatively different metallicity trends for high-mass galaxies.

This comparison highlights that our extended MZR provides a crucial observational constraint for galaxy evolution models in a mass regime where the MZR is very sensitive to choices about the implementation of AGN feedback.
