| 英文摘要 | This is the second paper of our series of works of studying the effects of active galactic nuclei (AGNs) feedback on the cosmological evolution of an isolated elliptical galaxy by performing two-dimensional hydrodynamical simulations. Compared to previous works, the main improvement here is that we adopt the most up-to-date AGN physics, which is described in detail in the first paper, including the discrimination of the two accretion modes and the most up-to-date descriptions of the wind and radiation in the two modes. In Paper I, we consider the case that the specific angular momentum of the gas in the galaxy is very low. In this paper, we consider the case that the specific angular momentum of the gas is high. At the galactic scale, we adopt the gravitational torques raised due to non-axisymmetric structure in the galaxy as the mechanism of the transfer of angular momentum of gas, as proposed in some recent works. Because our simulations are axisymmetric, we make use of a parameterized prescription to mimic this mechanism. Special attention is paid to the effects of specific angular momentum of the galaxy on the AGN light curve, growth of the black hole mass, AGN duty-cycle, star formation, and the X-ray surface brightness. We find that some results are qualitatively similar to those shown in Paper I, while other results, such as star formation and black hole growth, show a significant difference due to the mass concentration in the galactic disk as a consequence of galactic rotation. |
