论文摘要
通过当前的干涉测量实验从二元紧凑型恒星聚结的引力波发现了引力波天体物理学和宇宙学的新时代。通过将Ligo，处女座和Kagra形成的检测器网络中的一对检测器的信号相关联，正在搜索随机重力波背景。在先前的工作中，我们开发了一种基于球形谐波膨胀的方法，以计算Ligo-Virgo-Kagra网络的重叠降低功能，以用于两极分化的随机重力波背景。在这项工作中，我们将采用该方法来计算第三代探测器的重叠函数，例如将爱因斯坦望远镜，宇宙资源管理器和Lisa-Taiji联合空间任务联系起来的地面网络。
The detection of gravitational waves from the coalescences of binary compact stars by current interferometry experiments has opened up a new era of gravitational-wave astrophysics and cosmology. The search for a stochastic gravitational-wave background is underway by correlating signals from a pair of detectors in the detector network formed by the LIGO, Virgo, and KAGRA. In a previous work, we have developed a method based on spherical harmonic expansion to calculate the overlap reduction functions of the LIGO-Virgo-KAGRA network for a polarized stochastic gravitational-wave background. In this work, we will apply the method to calculate the overlap reduction functions of third-generation detectors such as a ground-based network linking the Einstein Telescope, the Cosmic Explorer, and the LISA-Taiji joint space mission.
