标题： Shapes and orientations of massive halos in the statistically anisotropic universe

摘要： 我们研究了物质分布中的统计各向异性（SA）如何影响集群大小的晕轮形状和取向，使用了包含SA的宇宙学$N$体模拟。 虽然三维晕轮形状参数对SA的依赖性很小，但我们发现晕轮取向受到显著影响，晕轮倾向于与SA方向垂直或平行对齐。 这种由SA引起的对齐对于更大量的晕轮更加明显。 我们的发现表明，从星系团-星系透镜效应中得出的投影晕轮形状的观测测量值可以为宇宙中的SA提供一种新的探测方法。 显示英文摘要

摘要： We investigate how statistical anisotropy (SA) in matter distributions affects the shapes and orientations of cluster-sized halos, using cosmological $N$-body simulations that incorporate SA. While the three-dimensional halo shape parameters show little dependence on SA, we find that halo orientations are significantly influenced, with halos tending to align either perpendicular or parallel to the SA direction. This SA-induced alignment becomes more prominent for more massive halos. Our findings suggest that observational measurements of projected halo shapes, such as those derived from galaxy cluster-galaxy lensing, could provide a novel probe of SA in the universe.
