论文摘要
高级LIGO-VIRGO探测器对重力波（GWS）的观察为我们提供了突破性的机会，以测试强大田间制度中爱因斯坦一般相对论（GR）的预测。在本文中，我们总结了对第三个GW瞬态目录GWTC-3中包含的新GW信号进行的GR的九项测试。这些测试包括与数据一起对信号的总体和自洽检查； GW产生，传播和极化的测试；以及通过测试BH响声假设并寻找合并后回声来探测残留物体的性质。新事件的结果与以前可能在可能的情况下发布的结果结合使用。我们没有发现与GR有任何统计学意义的偏差，并在可能与理论的偏离方面设定了最严格的界限。
Observations of gravitational waves (GWs) by the advanced LIGO--Virgo detectors provide us with ground breaking opportunities to test predictions of Einstein's theory of general relativity (GR) in the strong field regime. In this article, we summarise the nine tests of GR performed on the new GW signals included in the third GW transient catalog, GWTC-3. These tests include overall and self-consistency checks of the signal with the data; tests of the GW generation, propagation and polarizations; and probes of the nature of the remnant object by testing the BH ringdown hypothesis and searching for post-merger echoes. The results from the new events are combined with those previously published wherever possible. We do not find any statistically significant deviation from GR and set the most stringent bounds yet on possible departures from theory.
