Feedback from supermassive black holes (SMBHs) is believed to be a criticaldriver of the observed quenching of star formation and color bimodality ofgalaxies above the Milky Way mass scale. In recent years, various forms of SMBHfeedback have been implemented as subgrid models in galaxy formationsimulations, but most implementations have involved simplified prescriptions orcoarse-grained models of the interstellar medium (ISM). We present the firstset of FIRE-3 cosmological zoom-in simulations with AGN feedback evolved to$z\sim0$, examining a set of galaxies with halos in the mass range$10^{12}-10^{13}\,{\rm M_{\odot}}$. These high-resolution simulations combinedetailed stellar and ISM physics with multi-channel AGN feedback includingradiative feedback, mechanical outflows, and in some simulations, cosmic rays.We find that massive (>L*) galaxies in these simulations can match localscaling relations including the stellar mass-halo mass relation, the $M_{\rmBH}$-$\sigma$ relation, the size-mass relation, and the Faber-Jackson relation.Many of the massive galaxies in the simulations with AGN feedback have quenchedstar formation and elliptical morphologies, in qualitative agreement withobservations. In contrast, simulations at the massive end without AGN feedbackproduce galaxies that are too massive and form stars at too high rates, areorder-of-magnitude too compact, and have velocity dispersions well aboveFaber-Jackson. Despite these successes, the AGN physics models analyzed do notnecessarily produce uniformly realistic galaxies across the full mass rangestudied when the feedback parameters are held constant, indicating that furtherrefinements of the black hole modeling may be warranted.
