论文摘要
引力波回声为黑洞的量子性质提供了我们最直接，最令人惊讶的观察窗口。三年前，首次搜索来自普朗克规模的变化，对黑洞事件的一般相对性的修改，导致暂定证据，以1 \％arxiv的错误检测概率：1612.00266。该研究介绍了一个天真的现象学模型，并使用了第一个观察到的运行O1（GW150914，GW151226和LVT151012，现在GW151012）的第一个观测运行O1（GW150914，GW151226，GW151226），使用了公共数据发布。在这里，我们对独立组的各种观察性搜索进行了状态更新，并认为如果回声在较低的频率和/或在更极端质量比的二进制合并中最突出，则它们都可以保持一致。我们还指出，在二进制中子星级合并GW170817 ARXIV：1803.10454之后，唯一报告的回声（具有$>4σ$置信度）的“检测”（$>4σ$置信度）与电磁观测值推论的黑洞的形成时间相吻合。
Gravitational wave echoes provide our most direct and surprising observational window into quantum nature of black holes. Three years ago, the first search for echoes from Planck-scale modifications of general relativity near black hole event horizons led to tentative evidence at false detection probability of 1\% arXiv:1612.00266 . The study introduced a naive phenomenological model and used the public data release by the Advanced LIGO gravitational wave observatory for the first observing run O1 (GW150914, GW151226, and LVT151012, now GW151012). Here, we provide a status update on various observational searches for echoes by independent groups, and argue that they can all be consistent if echoes are most prominent at lower frequencies and/or in binary mergers of more extreme mass ratio. We also point out that the only reported "detection" of echoes (with $>4σ$ confidence) at 1.0 second after the binary neutron star merger GW170817 arXiv:1803.10454 is coincident with the formation time of the black hole inferred from electromagnetic observations.
