We investigate the environmental dependence of the mass-metallicity relation at z = 2 with MOSFIRE/Keck as part of the ZFIRE survey. Here, we present the chemical abundance of a Virgo-like progenitor at z = 2.095 that has an established red sequence. We identified 43 cluster (〈z〉 = 2.095 ± 0.004 ) and 74 field galaxies (〈z〉 = 2.195 ± 0.083) for which we can measure metallicities. For the first time, we show that there is no discernible difference between the mass-metallicity relation of field...[Show more]
