超大质量黑洞和它们的环境之间的共同演化最直接地被暗物质晕的热大气层所追踪。热大气的冷却为中心区域提供了新鲜气体，点燃了具有长占空比的活动星系核（AGN）。中央发动机的流出物与周围的气态介质紧密耦合，并提供主要的热源，通过雕刻空腔和驱动介质上的冲击来防止失控的冷却。活动星系核反馈环是所有现代星系演化模型的关键特征。在这里，我们回顾我们的知识的活动星系核反馈过程中的特定背景下的星系群。星系群是唯一适合约束控制冷热平衡的机制。与更大质量的晕不同，活动星系核中心提供给热的群内介质的能量可以超过晕气体粒子的引力结合能。我们报告的状态的最先进的反馈现象的观测和星系群中的加热-冷却平衡的理论模型。我们还描述了我们的知识的活动星系核反馈过程的影响星系演化模型和大规模的重子分布。最后，我们将讨论新的仪器将如何回答关键的开放问题的主题。
The co-evolution between supermassive black holes and their environment is most directly traced by the hot atmospheres of dark matter halos. The cooling of the hot atmosphere supplies the central regions with fresh gas, igniting active galactic nuclei (AGN) with long duty cycles. Outflows from the central engine tightly couple with the surrounding gaseous medium and provide the dominant heating source preventing runaway cooling by carving cavities and driving shocks across the medium. The AGN feedback loop is a key feature of all modern galaxy evolution models. Here, we review our knowledge of the AGN feedback process in the specific context of galaxy groups. Galaxy groups are uniquely suited to constrain the mechanisms governing the cooling–heating balance. Unlike in more massive halos, the energy that is supplied by the central AGN to the hot intragroup medium can exceed the gravitational binding energy of halo gas particles. We report on the state-of-the-art in observations of the feedback phenomenon and in theoretical models of the heating-cooling balance in galaxy groups. We also describe how our knowledge of the AGN feedback process impacts galaxy evolution models and large-scale baryon distributions. Finally, we discuss how new instrumentation will answer key open questions on the topic.
