标题： One-point Statistics in various cosmic environments in the presence of massive neutrinos

摘要： 研究宇宙环境（空洞、星系团和星系）中结构的形成（如晕和星系）是宇宙学研究中的持续尝试。结构属性与宇宙环境之间的联系可能有助于揭示宇宙暗物质领域的本质。在本文中，我们从空间模式的角度研究了标准模型的扩展——$ \Lambda $CDM 和$ \nu \Lambda $CDM 的宇宙网环境。为了做到这一点，我们使用了 T-web 分类方法，并对 gevolution N-body 模拟目录中的$ \Lambda $CDM 和$ \nu \Lambda $CDM 宇宙学的宇宙环境进行了分类。然后，我们计算了每个宇宙环境的第一个最近邻累积分布函数、球面接触累积分布函数和$ J$-函数。在标准模型的背景下，结果表明这些函数可以区分不同的宇宙环境。在区分宇宙学的标准模型扩展方面，这些函数作为补充探针似乎是有益的。 显示英文摘要

摘要： Studying the structures (halos and galaxies) within the cosmic environments (void, sheet, filament, and node) where they reside is an ongoing attempt in cosmological studies. The link between the properties of structures and the cosmic environments may help to unravel the nature of the dark sector of the Universe. In this paper, we study the cosmic web environments from the spatial pattern perspective in the context of $ \Lambda $CDM and $ \nu \Lambda $CDM as an example of an extension to the vanilla model. To do this, we use the T-web classification method and classify the cosmic environments for the catalogues from the gevolution N-body simulations for $ \Lambda $CDM and $ \nu \Lambda $CDM cosmology. Then, we compute the first nearest neighbour cumulative distribution function, spherical contact cumulative distribution function, and $ J$-function for every cosmic environment. In the context of the standard model, the results indicate that these functions can differentiate the various cosmic environments. In association with distinguishing between extensions of the standard model of cosmologies, these functions within the cosmic environment seem beneficial as a complementary probe.
