论文摘要
第三次观察高级LIGO和高级处女座的运行发生在2019年4月至2020年3月之间，导致了数十名引力波候选人，其中许多候选人现在以自信的检测出版。第三次观察的关键要求是对紧凑型二进制合并的快速识别和公开报告，这使得具有电磁和中微子观测值的大规模后续观察活动。 Pycbc Live是基于频域匹配的过滤的低延迟搜索紧凑型二进制合并，在第二和第三观察过程中已使用，以及其他低延迟分析，以从Ligo和Virgo获得的数据中生成这些快速的警报。本文介绍并评估了第二次观察后对Pycbc实时的改进，该进步在第三次观察过程中定义了其操作和性能。
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.
