Using a set of high-resolution simulations we study the statistical correlation of dark matter halo properties with the large-scale environment. We consider halo populations split into four Cosmic Web (CW) elements: voids, walls, filaments, and nodes. For the first time we present a study of CW effects for halos covering six decades in mass: $10^{8}-10^{14}{h^{-1}{\rm M}_{\odot}}$. We find that the fraction of halos living in various web components is a strong function of mass, with the majority of $M>10^{12}{h^{-1}{\rm M}_{\odot}}$ halos living in filaments and nodes. Low mass halos are more equitably distributed in filaments, walls, and voids. For halo density profiles and formation times we find a universal mass threshold of $M_{th}\sim6\times10^{10}{h^{-1}{\rm M}_{\odot}}$ below which these properties vary with environment. Here, filament halos have the steepest concentration-mass relation, walls are close to the overall mean, and void halos have the flattest relation. This amounts to $c_{200}$ for filament and void halos that are respectively $14\%$ higher and $7\%$ lower than the mean at $M=2\times10^8{h^{-1}{\rm M}_{\odot}}$, with low-mass node halos being most likely splashed-back. We find double power-law fits that very well describe $c(M)$ for the four environments in the whole probed mass range. A complementary picture is found for the average formation times, with the mass-formation time relations following trends shown for the concentrations: the nodes halos being the oldest and void halo the youngest. The CW environmental effect is much weaker when studying the halo spin and shapes. The trends with halo mass is reversed: the small halos with $M<10^{10}{h^{-1}{\rm M}_{\odot}}$ seem to be unaffected by the CW environment. Some weak trends are visible for more massive void and walls halos, which, on average, are characterized by lower spin and higher triaxiality parameters.

宇宙网是宇宙中最大尺度上星系和暗物质分布的最显著特征之一。它由密集的区域组成,充满了星系,长长的星系桥,扁平的薄片和巨大的低密度空洞。对宇宙网的研究主要集中在识别这些特征,以及理解环境对星系形成和晕组装的影响。因此,已经设计了各种不同的方法来对宇宙网进行分类-取决于手头的数据,无论是数值模拟,大型天空调查还是其他。在本文中,我们将这些方法中的12种方法放在一起,并将它们应用于同一数据集,以了解它们是如何比较的。一般来说,这些宇宙网络分类器是根据不同的宇宙学目标设计的,并研究不同的问题。因此,人们不会{ \it a priori}期望不同技术之间的一致性,然而,这些方法中的许多确实收敛于特定特征的识别。在本文中,我们研究的协议和不同的方法的差异。例如,每种方法都发现结比细丝等占据更高的密度区域,而空隙具有最低的密度。对于一个给定的网络环境,我们发现大量的重叠,在密度范围内分配的每个网络分类方案。我们还比较了一个光环光环的基础上的分类,例如,我们发现,12种方法中的9种将大约三分之一的群质量光环(即$M_{\rm halo}\sim10^{13.5}h^{-1}M_{\odot}$)分类为细丝。最后,为了使任何未来的宇宙网分类方案都可以与本文使用的12种方法进行比较,我们公开了本文中使用的所有数据。
