论文摘要
引力波(GW)的回声(如果存在)将是对黑洞的近晶体物理学的探测。在这份简短的报告中,我们进行了蒙特卡洛马尔可夫链分析,以在所有GWTC-1和O3 GW事件中搜索回声信号。我们专注于卑鄙的合并回波(IMRE)波形,并应用贝叶斯模型选择以将IMRE结果与IMR的结果进行比较。我们发现GW回声没有统计学意义($ <1σ$组合)的证据,并且只有单独的GW事件,其回声为$ 1 \ sim2σ$意义。
Gravitational wave (GW) echoes, if they exist, would be a probe to the near-horizon physics of black hole. In this brief report, we performed the Monte Carlo Markov Chain analysis to search for echo signal in all GWTC-1 and O3 GW events. We focus on the Insprial-Merger-Ringdown-Echo (IMRE) waveform, and apply the Bayesian model selection to compare the IMRE result with IMR's (no echo). We find no statistically significant ($<1σ$ combined) evidence for the GW echoes and only individual GW events with the echoes at $1\sim 2σ$ significance.
