We find that at $z\sim1. 5$, the average metallicity of galaxies in overdensities with $M_*\sim10^{9. 8}M_\odot, 10^{10. 2}M_\odot$ and $10^{10. 8}M_\odot$ is higher relative to their field counterparts by $0. 094\pm0. 051$, $0. 068\pm0. 028$ and $0. 052\pm0. 043$ dex, respectively.

It is widely reported, based on clustering measurements of observed active galactic nuclei (AGN) samples, that AGN reside in similar mass host dark matter halos across the bulk of cosmic time, with log $M/M_\odot$~12. 5-13. 0 to z~2. 5.
