论文摘要
2016年2月11日，Ligo和处女座的科学合作宣布了首次直接检测引力波，这是Ligo干涉仪于2015年9月14日捕获的信号，并由两个恒星质量黑洞的合并产生。该发现代表了研究宇宙的全新方式的开始。 Ligo，处女座和Kagra的最新重力波目录将重力波事件的总数提高到90，并且预计未来几年的计数将显着增加，届时额外的基于地面和太空的干预仪将运行。从理论的角度来看，我们对检测事件的来源只有模糊的想法，对五个WS的大多数答案以及紧凑型二元合并的天体物理学的答案仍然未知。在这项工作中，我们回顾了当前关于合并紧凑型二进制二进制的天体物理过程的知识和不确定性。此外，我们通过最新的重力波检测来讨论从最新的重力波检测中学到的天体物理经验教训，并特别注意来自特殊事件的理论挑战（例如，GW190521和GW190814）。
On 11 February 2016, the LIGO and Virgo scientific collaborations announced the first direct detection of gravitational waves, a signal caught by the LIGO interferometers on 14 September 2015, and produced by the coalescence of two stellar-mass black holes. The discovery represented the beginning of an entirely new way to investigate the Universe. The latest gravitational-wave catalog by LIGO, Virgo and KAGRA brings the total number of gravitational-wave events to 90, and the count is expected to significantly increase in the next years, when additional ground-based and space-born interferometers will be operational. From the theoretical point of view, we have only fuzzy ideas about where the detected events came from, and the answers to most of the five Ws and How for the astrophysics of compact binary coalescences are still unknown. In this work, we review our current knowledge and uncertainties on the astrophysical processes behind merging compact-object binaries. Furthermore, we discuss the astrophysical lessons learned through the latest gravitational-wave detections, paying specific attention to the theoretical challenges coming from exceptional events (e.g., GW190521 and GW190814).
