使用PyCBC Live在Advanced LIGO和Virgo的第三次观测运行中实时搜索紧凑的二元合并
Realtime search for compact binary mergers in Advanced LIGO and Virgo's third observing run using PyCBC Live
摘要：
Advanced LIGO和Advanced Virgo的第三次观测运行发生在2019年4月至2020年3月之间，产生了数十个引力波候选者，其中许多现在已被公布为可靠的探测。第三次观测的一个关键要求是快速识别和公开报道紧凑的双星合并，这使得电磁和中微子观测站能够进行大规模的后续观测活动。PyCBC Live是一种基于频域匹配滤波的紧凑二进制合并的低延迟搜索，已在第二次和第三次观测运行期间使用，以及其他低延迟分析，以从LIGO和Virgo获取的数据中生成这些快速警报。本文描述并评估了第二次观察运行后对PyCBC Live所做的改进，这些改进定义了第三次观察运行期间的操作和性能。
英文摘要：
The third observing run of Advanced LIGO and Advanced Virgo took place between April 2019 and March 2020 and resulted in dozens of gravitational-wave candidates, many of which are now published as confident detections. A crucial requirement of the third observing run has been the rapid identification and public reporting of compact binary mergers, which enabled massive followup observation campaigns with electromagnetic and neutrino observatories. PyCBC Live is a low-latency search for compact binary mergers based on frequency-domain matched filtering, which has been used during the second and third observing runs, together with other low-latency analyses, to generate these rapid alerts from the data acquired by LIGO and Virgo. This paper describes and evaluates the improvements made to PyCBC Live after the second observing run, which defined its operation and performance during the third observing run.
