Gravitational wave (GW) observations provide sensitive tests of parity and Lorentz symmetries of gravity. Any violation of these fundamental symmetries induces possible deviations in the GW propagations. Through a systematic parametrization for characterizing possible derivations from GW propagations in general relativity, we construct the modified GW waveforms generated by the coalescence of compact binaries with the effects of the parity and Lorentz violations as predicted by many parity- and Lorentz-violating gravities and then analyze them with the open data of compact binary merging events detected by LIGO-Virgo-KAGRA Collaboration. No signature of gravitational parity and Lorentz violations is found for most GW events, thereby allowing us to place several of the most stringent constraints on parity and Lorentz violations in gravity and a first constraint on the Lorentz-violating damping effect in GW.

通过修改引力波传播的参数化，对 GWTC-3 中的宇称和洛伦兹违规进行约束


引力波（GW）观测提供了对引力宇称和洛伦兹对称性的灵敏测试。任何对这些基本对称性的违反都会导致引力波传播可能出现偏差。通过系统参数化来表征广义相对论中引力波传播的可能推导，我们构建了由致密双星合并产生的修改后的引力波波形，以及宇称和洛伦兹违规引力所预测的宇称和洛伦兹违规的影响，然后使用 LIGO-Virgo-KAGRA 协作检测到的紧凑双星合并事件的开放数据对其进行分析。对于大多数引力波事件，没有发现引力宇称和洛伦兹违规的特征，从而允许我们对引力宇称和洛伦兹违规设置几个最严格的约束，并对引力波中洛伦兹违规阻尼效应设置第一个约束。
