我们描述了一种方法，用于搜索瞬态引力波与软伽马射线中继器（SGR）耀斑或其他突发事件使用干涉引力波探测器收集的数据。该方法可用于分析来自单个探测器或来自两个探测器的相干数据。过功率型算法从调节的检测器数据创建事件集，其可以基于合理的波形类与已知强度的信号模拟进行比较。给出了通过对模拟数据执行两个检测器搜索获得的估计搜索灵敏度。在将100-200 Hz频带中的22 ms持续时间的白色噪声脉冲串注入模拟噪声的情况下，我们发现特征应变灵敏度h90%rss = 3.0 × 10−22。
We describe a method for searching for transient gravitational waves associated with soft gamma-ray repeater (SGR) flares or other burst-like events using data collected by interferometric gravitational wave detectors. The method can be used to analyze data from either a single detector or from two detectors coherently. The excess power-type algorithm creates event sets from conditioned detector data which may be compared to signal simulations of known strength based on plausible waveform classes. Estimated search sensitivities obtained by performing two-detector searches on the simulated data are presented. In the case of 22 ms duration white noise bursts in the 100–200 Hz band injected into simulated noise, we find a characteristic strain sensitivity h90%rss = 3.0 × 10−22 .
