论文摘要
在这项工作中，使用高斯工艺，我们通过比较其不透明度的无透明度距离（LD）与依赖于IA型超级Novae（SNIA）类型（SNIA）和Gamma-Ray Ray Ray Ray Ray usbers（Grbs）的不透明度相关的无不透明度亮度距离（LD）来探讨未来重力波（GW）测量对探测宇宙不透明度的潜力。 GW数据，SNIA和GRB数据分别从Einstein望远镜的测量结果，实际的万神殿汇编以及分别由L. amati {\ it等人对GRB的最新观察结果进行了模拟。提出了一种非参数方法来探测高红移时宇宙透明度的空间均匀性，通过比较从GW数据重建的LD与 从万神殿和GRB数据重建。此外，通过使用光学深度的参数化测试宇宙不透明度，结果表明，宇宙不透明度的约束比以前的约束更为严格。它表明，未来的GW测量值可以用作探测高红移区域宇宙不透明度的重要工具。
In this work, using the Gaussian process, we explore the potentiality of future gravitational wave (GW) measurements to probe cosmic opacity at high redshifts through comparing its opacity-free luminosity distance (LD) with the opacity-dependent one from the combination of Type Ia supernovae (SNIa) and gamma-ray bursts (GRBs). The GW data, SNIa and GRB data are simulated from the measurements of the future Einstein Telescope, the actual Pantheon compilation and the latest observation of GRBs compiled by L. Amati {\it et al}, respectively. A nonparametric method is proposed to probe the spatial homogeneity of cosmic transparency at high redshift by comparing the LD reconstructed from the GW data with that reconstructed from the Pantheon and GRB data. In addition, the cosmic opacity is tested by using the parametrization for the optical depth, and the results show that the constraints on cosmic opacity are more stringent than the previous ones. It shows that the future GW measurements may be used as an important tool to probe the cosmic opacity in the high redshift region.
