先进探测器的低延迟引力波瞬态搜索

Low Latency transient search of Gravitational Waves for the Advanced Detectors

Marco Drago

摘要:

第一次探测的可靠性是引力波界最感兴趣的挑战之一。为了增加探测的可信度,LIGO和Virgo合作已经开始在引力波探测器和其他天文仪器(如电磁或中微子探测器)之间进行同步观测。这可以从两个方向进行:搜寻电磁信息触发的引力波,或者将电磁望远镜指向引力波分析实时给出的天空位置。后一种情况的成功在很大程度上取决于引力波管道的分析速度,以分析数据并提取具有尽可能多信息的任何引力波候选。在本文中,我们讨论的情况下,相干Waveburst管道,在过去的科学LIGO-Virgo分析搜索的引力波瞬变的主要管道,报告的能力,使一个全天和所有时间的分析和分析速度性能。

英文摘要:

The reliability of the first detection is one of the most interesting challenges for the gravitational wave community. To increase the detection confidence, the LIGO and Virgo collaborations have already started coincident observations between gravitational waves detectors and other astronomical instruments, like electromagnetic or neutrino detectors. This can be done in two directions: searching for gravitational waves triggered by the electromagnetic information, or pointing the electromagnetic telescopes to the sky position given in real time by the gravitational wave analysis. The success of the latter case depends strongly on the analysis speed of gravitational wave pipelines to analyze data and extract any gravitational wave candidate with as much information as possible. In this paper we discuss the case of the coherent Waveburst pipeline, the main pipeline used in the past scientific LIGO-Virgo analyses for the search of gravitational wave transients, reporting the capability of making an all-sky and all-time analysis and the analysis speed performance.
