The Zeldovich approximation: key to understanding Cosmic Web complexity
Johan Hidding, Sergei F. Shandarin, Rien van de Weygaert
We describe how the dynamics of cosmic structure formation defines the intricate geometric structure of the spine of the cosmic web. The Zeldovich approximation is used to model th…
Betti numbers of Gaussian fields
Changbom Park, Pratyush Pranav, Pravabati Chingangbam +6
We present the relation between the genus in cosmology and the Betti numbers for excursion sets of three- and two-dimensional smooth Gaussian random fields, and numerically investi…
Alpha, Betti and the Megaparsec Universe: on the Topology of the Cosmic Web
Rien van de Weygaert, Gert Vegter, Herbert Edelsbrunner +13
We study the topology of the Megaparsec Cosmic Web in terms of the scale-dependent Betti numbers, which formalize the topological information content of the cosmic mass distributio…
