标题： AGN Feedback Mechanisms

摘要： 吸积黑洞可以以各种形式向其周围释放巨大的能量。这种反馈可能会深刻影响黑洞的环境。在简要回顾了可能的反馈类型之后，我重点关注通过喷流和强风注入动能。这些外流的影响在加热弥漫于星系团的X射线发射大气时可能尤为明显。在星系形成的时期，类似的加热效应可能调控超大质量黑洞的增长。 显示英文摘要

摘要： Accreting black holes can release enormous amounts of energy to their surroundings, in various forms. Such feedback may profoundly influence a black hole's environment. After briefly reviewing the possible types of feedback, I focus on the injection of kinetic energy through jets and powerful winds. The effects of these outflows may be especially apparent in the heating of the X-ray--emitting atmospheres that pervade clusters of galaxies. Analogous heating effects, during the epoch of galaxy formation, could regulate the growth of supermassive black holes.
