数值模拟中的AGN反馈

AGN feedback in numerical simulations

L. Ciotti

摘要:

椭圆星系(Es)中被动演化的恒星星族为中心超大质量黑洞(SMBH)的吸积提供了持续的燃料源,这种吸积作用贯穿整个星系生命周期(但随着宇宙时间的推移而下降),2)与宿主球体的恒星质量成线性比例,3)加起来的总气体质量比目前观测到的SMBH质量大100倍,4)独立于合并事件可用。的主要结果的数值模拟的Es与中央SMBH,其中被认为是一个物理为基础的实施辐射和机械反馈效应,提出。

英文摘要:

The passively evolving stellar population in elliptical galaxies (Es) provides a continuous source of fuel for accretion on the central supermassive black hole (SMBH), which is 1) extended over the entire galaxy life (but declining with cosmic time), 2) linearly proportional to the stellar mass of the host spheroid, 3) summing up to a total gas mass that is >100 times larger than the currently observed SMBH masses, 4) available independently of merging events. The main results of numerical simulations of Es with central SMBH, in which a physically based implementation of radiative and mechanical feedback effects is considered, are presented.
