论文摘要
我们开发了一种通用数据驱动和模板的方法，用于在存在背景噪声的情况下提取事件波形。最近的重力波观测提供了需要数据分析和波形提取能力的重要科学领域之一。我们使用我们的方法来找到从第一，第二和第三分支观测运行（O1，O2和O3）中报告的事件的波形。使用提取波形的希尔伯特变换得出的瞬时频率，我们提供了引力波到达检测器的物理时间延迟。
We develop a general data-driven and template-free method for the extraction of event waveforms in the presence of background noise. Recent gravitational-wave observations provide one of the significant scientific areas requiring data analysis and waveform extraction capability. We use our method to find the waveforms for the reported events from the first, second, and third LIGO observation runs (O1, O2, and O3). Using the instantaneous frequencies derived by the Hilbert transform of the extracted waveforms, we provide the physical time delays between the arrivals of gravitational waves to the detectors.
