Metallicities in cosmological simulations with AGN feedback
Abstract
In our cosmological, chemodynamical simulations, (i) the black hole mass-velocity dispersion relation does not evolve, and black holes actually grow along the relation. (ii) the stellar mass-metallicity relation does not change its shape, while the gas-phase relation has a steeper slope at higher redshifts. (iii) While stellar metallicity gradients are made shallower by galaxy mergers, gas-phase gradients are affected more strongly by AGN feedback.
