论文摘要
我们提出了一个新的基本物理探针，涉及探索多频电磁（EM）信号与阈值GW信号或随机重力波背景（SGWB）之间的时间相关性。此方法将有助于检测与亚阈值/SGWB信号相关的EM对应物。利用引力波和EM信号的同时发射之间的时间延迟可以通过研究由于宇宙学扩张而引起的时间延迟扩张来推断贡献来源的红移，前提是，如果重力波信号的发射与EM信号的发射之间的时间段与标准时钟的表现。测量重力和EM波的不同频率之间不可避免的时间域相关性，最著名的是在伽马射线中，将测试基本物理学和引力理论的几个方面，并为当前和未来的引力望远镜提供新的途径，以研究研究二进制压缩物体的通用性质的通用性质，从而使高速度的普遍性。
We propose a novel probe of fundamental physics that involves the exploration of temporal correlations between the multi-frequency electromagnetic (EM) signal and the sub-threshold GW signal or stochastic gravitational wave background (SGWB) originating from coalescing binaries. This method will be useful for the detection of EM counterparts associated with the sub-threshold/SGWB signal. Exploiting the time delay between concomitant emission of the gravitational wave and EM signals enables inference of the redshifts of the contributing sources by studying the time delay dilation due to cosmological expansion, provided that the time-lag between the emission of gravitational wave signal and the EM signal acts like a standard clock. Measurement of the inevitable time-domain correlations between different frequencies of gravitational and EM waves, most notably in gamma-rays, will test several aspects of fundamental physics and gravitation theory, and enable a new pathway for current and future gravitational wave telescopes to study the universal nature of binary compact objects to high redshifts.
