AI 中文总结
本文对O3中G347.3-0.5的连续引力波异常源开展多管道后续研究，确认其在O3中存在，O4a、O4b中无相关标准信号，为CW候选体多管道后续研究提供测试案例。
AI 中文摘要
我们对由Ming等人通过Einstein@Home定向搜索在年轻超新星遗迹G347.3-0.5（包含中心致密天体RXJ1713.7-3946）中识别出的连续引力波（CW）异常源开展了多管道后续研究。该异常源最初在O3观测运行的LIGO数据中被识别，随后通过Einstein@Home管道加入O3b和O4a数据进行后续研究，其中O4a产生的证据较弱。本文展示了扩展的数据质量检查结果，以及三个独立研究该异常源的管道的结果，包括新发布的O4b数据集。我们能在O3中可靠地恢复该异常源，而在O4a（与Ming等人的结论一致）和O4b数据中未发现相关标准CW信号的证据。本研究可作为未来CW候选体多管道后续研究的有用测试案例，旨在探究其天体物理性质或噪声性质，因此是首次CW探测准备工作中的重要一步。
英文摘要
We report a multi-pipeline follow-up study of the continuous gravitational-wave (CW) outlier identified by the Ming et al. Einstein@Home directed search for the young supernova remnant G347.3-0.5 (containing the central compact object RXJ1713.7-3946). The outlier was initially identified in LIGO data from the O3a observing run and followed up with the addition of O3b and O4a data by the Einstein@Home pipeline, with O4a producing weaker evidence. Here, we show extended data quality checks and results from three pipelines that have independently investigated this outlier, including the newly released O4b data set. We can robustly recover the outlier in O3, while we find no evidence for a related standard CW signal in O4a (consistent with Ming et al.) and O4b data. This work serves as a useful test case for future multi-pipeline follow-ups of CW candidates that aim to investigate their astrophysical or noise nature, and it is therefore an important step in preparation for the first CW detection.
