星系核中心有一个超大质量黑洞（SMBH），可能被一个密集的核团（NC）包围，代表了极端的环境，其中包含了许多物理过程的复杂相互作用，这些物理过程独特地影响着恒星的形成、演化和动力学。黑洞（BHs）和中子星（NSs）合并发出的引力波（GWs）的发现，汇集了大量的工作，重点是了解紧凑的双星（cob）如何配对并合并在一起。在这里，我们从理论的角度回顾了静止的SMBHs和活动的星系核（agn）周围的COBs形成、演化和合并的不同机制，总结了当前和未来（GW）探测的主要预测，并概述了可能标志星系核起源的可能特征。
Galactic nuclei harbouring a central supermassive black hole (SMBH), possibly surrounded by a dense nuclear cluster (NC), represent extreme environments that house a complex interplay of many physical processes that uniquely affect stellar formation, evolution, and dynamics. The discovery of gravitational waves (GWs) emitted by merging black holes (BHs) and neutron stars (NSs), funnelled a huge amount of work focused on understanding how compact object binaries (COBs) can pair up and merge together. Here, we review from a theoretical standpoint how different mechanisms concur with the formation, evolution, and merger of COBs around quiescent SMBHs and active galactic nuclei (AGNs), summarising the main predictions for current and future (GW) detections and outlining the possible features that can clearly mark a galactic nuclei origin.
