标题： Fast evaluation of multi-detector consistency for real-time gravitational wave searches

摘要： 使用LIGO和Virgo探测器寻找致密双星并合的引力波信号目前是一个两阶段过程。首先，识别出引力波信号；然后，对可能的信号参数进行全面搜索。为了最大化被识别的引力波源数量，识别阶段必须高效。利用LIGO和Virgo进行初始实时引力波信号识别需要满足每收集一秒的引力波数据，计算时间不超过一秒的要求。相比之下，后续的参数估计可能需要数百小时的计算时间来分析相同的一秒引力波数据。实时识别要求采用高效且通常是近似的信号分析方法。我们描述了实时引力波识别的一部分：一种用于确认多个引力波探测器间信号一致性的有效方法，适用于实时致密双星并合的引力波搜寻。该技术在高级LIGO第二观测运行和高级Virgo第一观测运行的分析中得到了应用。 显示英文摘要

摘要： Gravitational waves searches for compact binary mergers with LIGO and Virgo are presently a two stage process. First, a gravitational wave signal is identified. Then, an exhaustive search over possible signal parameters is performed. It is critical that the identification stage is efficient in order to maximize the number of gravitational wave sources that are identified. Initial identification of gravitational wave signals with LIGO and Virgo happens in real-time which requires that less than one second of computational time must be used for each one second of gravitational wave data collected. In contrast, subsequent parameter estimation may require hundreds of hours of computational time to analyze the same one second of gravitational wave data. The real-time identification requirement necessitates efficient and often approximate methods for signal analysis. We describe one piece of real-time gravitational-wave identification: an efficient method for ascertaining a signal's consistency between multiple gravitational wave detectors suitable for real-time gravitational wave searches for compact binary mergers. This technique was used in analyses of Advanced LIGO's second observing run and Advanced Virgo's first observing run.
