The observation of GW150914 indicated a new independent measurement of the luminosity distance of a gravitational wave event. In this paper, we constrain the anisotropy of the Universe by using gravitational wave events. We simulate hundreds of events of binary neutron star merging that may be observed by Einstein Telescope. Full simulation for producing process of gravitational wave data is employed. We find that 200 of binary neutron star merging in redshift $(0,1)$ observed by Einstein Telescope may constrain the anisotropy with an accuracy comparable to the result from Union2.1 supernovae. This result shows that gravitational waves can be a powerful tool in investigating the cosmological anisotropy.
Prospects of LIGO for constraining inclination of merging compact binaries associated with three-dimensionally localized short-hard GRBs
我们研究了通过探测与三维局部（方向和距离）短硬伽马射线暴相关的引力波来限制合并致密双星倾角的方法的前景。我们利用这两个观测的协同作用，我们的方法甚至可以应用于单个干涉仪。对于近正面双星，只要距离估计的误差可以忽略，倾角$I$可以限制在1-1/SNR < cosI \le 1（SNR：引力波探测的信噪比）的范围内。这种方法将有助于我们研究短硬爆发的性质，包括最近的观测表明的潜在准直喷流状结构。

Constraining Anisotropic Cosmological Model in $f(\mathcal{R},\mathscr{L}_m)$ Gravity
关于目前宇宙学方面的观测证据告诉我们，在大尺度上，宇宙中存在着非常小的各向异性。在本文中，我们试图研究具有各向同性物质分布的局部旋转对称（LRS）均匀Bianchi-I时空。这是在$f(\mathcal{R},\mathscr{L}_m)$重力框架内完成的。特别地，我们考虑一个非线性$f(\mathcal{R},\mathscr{L}_m)$模型，$f(\mathcal{R},\mathscr{L}_m)=\dfrac{1}{2}\mathcal{R}+\mathscr{L}_m^{\,α}$。此外，状态方程参数$ω$，这是在确定宇宙的当前阶段的重要材料是受约束的。为了约束模型参数和状态方程参数，我们使用了57个哈勃数据点和1048个Pantheon Ia型超新星数据样本。并且，对于我们的统计分析，我们使用Markoc Chain Monte Carlo（MCMC）模拟。此外，在所获得的参数值的帮助下，我们测量了我们的模型的各向异性参数。
