Abstract: We propose a new black hole feedback algorithm for the GASOLINE-based cosmological Zoom-in simulations, focusing on two feedback modes: thermal feedback for high-accretion rates, which heats the surrounding gas, while kinetic feedback for low-accretion rates, which imparts momentum to simulate AGN-driven outflows and jets. Both modes incorporate realistic opening angles to better model the complex gas dynamics near the black hole, leading to a more physically realistic representation of galaxy evolution. Our model has successfully fit across several cosmological scaling relations, such as stellar mass vs. halo mass and black hole mass vs. stellar mass, while also producing more rotation-supported, disk-like morphologies. These results are consistent with observational evidence and offer new insights into the development of galaxy evolution. While further refinement and testing are necessary, this model presents a promising tool for advancing our understanding of galaxy formation and evolution, particularly in high-mass elliptical galaxies. |
