论文摘要
介绍的是一种用于搜索引力波（GW）触发器的$γ$ ray对应物的新通用方法的描述。该方法专门应用于单个GW检测器触发器。分析了来自观察运行的O1和O2的高级LIGO数据，因此每个GW触发器都来自Ligo-Livingston或Ligo-Hanfore干涉仪。对于每个GW触发器，搜索费米伽马射线爆发监视器数据，并选择了最重要的子阈值信号对应物。然后，定义了一种方法，以确定哪个GW- $γ$ ray对可能具有共同的起源。为此，计算关联排名统计量，从中得出了错误的警报率。选择最高排名统计的事件以进行进一步的分析，该分析包括LIGO检测器表征和参数估计。还评估了$γ$ ray信号特性。我们没有发现搜索中的重要候选人。
Presented is the description of a new and general method used to search for $γ$-ray counterparts to gravitational-wave (GW) triggers. This method is specifically applied to single GW detector triggers. Advanced LIGO data from observing runs O1 and O2 were analyzed, thus each GW trigger comes from either the LIGO-Livingston or the LIGO-Hanford interferometer. For each GW trigger, Fermi Gamma-ray Burst Monitor data is searched and the most significant subthreshold signal counterpart is selected. Then, a methodology is defined in order to establish which of GW-$γ$-ray pairs are likely to have a common origin. For that purpose an association ranking statistic is calculated from which a false alarm rate is derived. The events with the highest ranking statistics are selected for further analysis consisting of LIGO detector characterization and parameter estimation. The $γ$-ray signal characteristics are also evaluated. We find no significant candidates from the search.
