摘要

LIGO和处女座探测器数据的公开发布使得独立团队能够使用替代方法识别潜在的引力波信号。除了LIGO-Virgo-KAGRA （LVK）合作的GWTC-3目录外，还有其他几个工作声称在前三次观测运行的数据中检测到信号。在本文中，我们使用与LVK发布的GWTC-2.1和GWTC-3目录相同的分析工作流程对这些新信号进行了分析，尽可能地匹配分析配置，并以与GWTC-3数据发布的格式相当的格式提供了参数估计结果，其中57个事件未在LVK分析中分析过。我们发现我们的结果与其他小组发表的结果大致一致。我们还讨论了为此分析开发的工作流程。

Beyond GWTC-3: analyzing and verifying new gravitational-wave events from community catalogues

The public release of data from the LIGO and Virgo detectors has enabled the identification of potential gravitational wave signals by independent teams using alternative methodologies. In addition to the LIGO-Virgo-KAGRA (LVK) collaboration’s GWTC-3 catalogue there have been several additional works claiming the detection of signals in the data from the first three observing runs. In this paper we present an analysis of these new signals using the same analysis workflow which was used to generate the GWTC-2.1 and GWTC-3 catalogues published by the LVK, matching the analysis configuration as closely as possible, and we provide our parameter estimation results in a format comparable to those of the GWTC-3 data release for 57 events not previously analyzed in LVK analyses. We find our results to be broadly consistent with those published by other groups. We also include a discussion of the workflow developed for this analysis.
