The recent observations of gravitational waves during the coalescence of black holes has confirmed various predictions of general relativity. However, some concerns have been raised that these putative waves are artifacts. We have analyzed the ten confident gravitational waves detected in Observation Run 1 (O1) and Observation Run 2 (O2) and the gravitational wave emitted by the single known example of a neutron star coalescence, all of which have been verified by the Advanced Laser Interferometer Gravitational Wave Observatory and/or the Advanced Virgo Collaboration. On three occasions both Advanced LIGO and Advanced Virgo detected the same event (Abbott et al., 2019).

Whitening of the Hanford data (Gravitational Wave Open Science Center) was employed in this study to reduce colored non-transient noise, but template matching was not employed. In each of the ten events mentioned above we verified the presence of such waves by the application of non-stationary data analysis via the Morlet wavelet. We examined the strain data before, during and after each wave. In each case we employed seven measures of complexity or information before, and during each wave and analyzed these data using doubly multivariate MANOVA, the appropriate statistical test for repeated measures (pre-wave vs wave). In addition we compared the strain data before and after the putative event to see if there was persistence of any effect of the event. In each case the information content was significantly elevated during the wave compared to similar time samples taken before the wave. No persistent effects on the strain data were noted after the event. We conclude our analysis is consistent with the actual detection of gravitational waves by the LIGO and Virgo Collaboration. Our results suggest black hole coalescence generates mathematically complex gravitational waves which may elucidate aspects of such coalescence.

最近对黑洞合并过程中引力波的观察证实了广义相对论的各种预测。然而，有人担心这些假定的波浪是伪影。我们分析了在观测运行 1 (O1) 和观测运行 2 (O2) 中检测到的十个可信引力波以及由中子星合并的单个已知示例发出的引力波，所有这些都已通过高级激光干涉仪的验证引力波天文台和/或高级处女座合作。Advanced LIGO 和 Advanced Virgo 先后三次检测到同一事件（Abbott 等，2019）。

本研究采用汉福德数据（引力波开放科学中心）的白化以减少有色非瞬态噪声，但未采用模板匹配。在上述十个事件中的每一个中，我们通过 Morlet 小波应用非平稳数据分析来验证此类波的存在。我们检查了每一波之前、之中和之后的应变数据。在每种情况下，我们在之前和每个波浪期间使用了七种复杂性或信息度量，并使用双多变量 MANOVA 分析了这些数据，这是对重复测量（前波与波）的适当统计检验。此外，我们比较了假定事件之前和之后的应变数据，以查看事件的任何影响是否持续存在。在每种情况下，与波浪之前采集的类似时间样本相比，波浪期间的信息内容显着增加。事件发生后没有注意到对应变数据的持续影响。我们得出的结论是，我们的分析与 LIGO 和 Virgo Collaboration 对引力波的实际探测是一致的。我们的结果表明黑洞合并会产生数学上复杂的引力波，这可能会阐明这种合并的各个方面。
