Journal ArticleDOI
A hierarchy of voids: much ado about nothing
TL;DR: In this article, the authors present a model for the distribution of void sizes and its evolution in the context of hierarchical scenarios of gravitational structure formation, and show that at any cosmic epoch the voids have a size distribution that is well-peaked about a characteristic void size that evolves self-similarly in time.
Journal ArticleDOI
Evolution of the cosmic web
TL;DR: In this article, the authors investigated the characteristics and the time evolution of morphological components of the cosmic web and employed new analysis techniques to determine the spatial extent of filaments and sheets, like their total length and local width.
Journal ArticleDOI
A cosmic watershed: the WVF void detection technique
TL;DR: The watershed void finder (WVF) as mentioned in this paper is based upon the watershed transform, a well-known technique for the segmentation of images, which has the potential to trace the existing manifestations of a void hierarchy.
Journal ArticleDOI
Spin alignment of dark matter haloes in filaments and walls
TL;DR: In this article, the authors used the MMF technique to segment the cosmic web as seen in a cosmological N-body simulation into wall-like and filament-like structures and found that the spins and shapes of dark matter haloes are significantly correlated with each other and with the orientation of their host structures.
