Description

I will present our recent numerical simulation results of the evolution of a disk galaxy with the effects of AGN feedback. The simulation is based on our MACER framework. Different from cosmological simulations, MACER focuses on galactic scale, thus has very high spacial resolution. The inner boundary of the simulation is smaller than the Bondi radius of the accretion flow so we can reliably calculate the black hole accretion rate. The state-of-the-art AGN physics is incorporated. We will show the simulation results on light curve of AGN luminosity (i.e., AGN duty-cycle), BHAR-SFR correlation, and the ratio of cold gas as a function of AGN luminosity and their comparison with observations. The quench mechanism will also be discussed.
