Feedback from stars and active galactic nuclei (AGN) is the most important process in galaxy formation and evolution. In our cosmological hydrodynamical simulations, we introduced a new AGN model, where super-massive blackholes originate the first stars with only ~100-1000 Msun, contrary to the merger products in other models. We also have chemical and thermal feedback from core-collapse supernovae (Type II supernovae and hypernovae), Type Ia supernovae, and asymptotic giant branch stars.
Our AGN feedback cause large-scale metal outflows and enrich circum-galactic and inter-galactic medium.
As a result, we can reproduce many observations well, including cosmic star formation rates, blackhole mass-galaxy mass relation, size-mass relation, mass-metallicity relations of galaxies, and radial metallicity gradients within galaxies.
