改善核坍缩超新星引力波搜索的本底:一种机器学习方法

摘要

基于先前的 O1-O2 观测运行,预计 Advanced LIGO 与 Virgo 在后续观测运行中收集的数据约有 30% 为单干涉仪数据,即这些数据是在网络中仅有一个探测器处于观测模式时收集的。由于信号的随机性质,针对超新星事件的引力波信号搜索并不依赖匹配滤波技术。若银河系超新星发生于单干涉仪时段,由于缺乏探测器间的相干性,将其未建模的引力波信号从噪声中分离将更为困难。我们提出了一种基于标准 LIGO-Virgo coherentWave-Burst 流水线的新型机器学习方法以执行单干涉仪超新星搜索。我们表明该方法可用于区分银河系引力波超新星信号与噪声瞬变,降低搜索的误报率,并提升探测器的超新星探测距离。
