论文摘要
我们描述了在第三次观察跑步（2019-2020）时，以低延迟检测和离线分析来描述来自Ligo-Virgo数据中紧凑型物体合并的引力波信号的多波段模板分析（MBTA）搜索引力波信号（MBTA）搜索引力波的多波段模板分析（MBTA）搜索引力波的搜索，我们描述了在第三次观察员（2019-2020），均用于低延期院检测和离线分析。提供有关管道的架构和功能的详细信息，包括瞬态降低噪声策略，搜索信号的参数空间，候选人的检测以及与与之相关的虚假警报率的评估。基于Ligo-Virgo第三观察跑步演示了低延迟搜索的性能，在此期间，MBTA贡献了42次警报，并提交了候选人的中位延迟36秒。在第二个Ligo-Virgo观察过程中收集的数据子集说明了离线搜索的性能，并根据对相同数据的模拟信号事件的注射进行量化。
We describe the Multi-Band Template Analysis (MBTA) search for gravitational waves signals from coalescences of compact objects in the LIGO-Virgo data, at the time of the third observing run (2019-2020), both for low-latency detections and for offline analysis. Details are given on the architecture and functioning of the pipeline, including transient noise mitigation strategies, parameter space for the searched signals, detection of candidates and evaluation of a false alarm rate associated to them. The performance of the low-latency search is demonstrated based on the LIGO-Virgo third observing run, during which MBTA has contributed to 42 alerts, submitting candidates with a median latency of 36 seconds. The performance of the offline search is illustrated on a subset of data collected during the second LIGO-Virgo observation run in 2017, and are quantified based on injections of simulated signal events on the same data.
