论文摘要
我们研究了随机引力波背景(SGWB)的强度和极化各向异性的干涉观察。我们表明,在三维旋转的组歧管中定义了观察到的相关数据。干涉测量实验(例如Ligo-Virgo和Kagra)中两个检测器之间的显式相关性是根据Wigner d功能构建的。我们的结果可能提供了一种用于构建数据管道的工具,以估计SGWB各向异性的功率光谱。
We study the interferometric observation of intensity and polarization anisotropies of a stochastic gravitational wave background (SGWB). We show that the observed correlated data is defined in the group manifold of the three-dimensional rotation. Explicit correlation between two detectors in the interferometry experiments such as LIGO-Virgo and KAGRA is constructed in terms of the Wigner D-functions. Our results may provide a tool for constructing data pipelines to estimate the power spectra of the SGWB anisotropies.
