The Cosmic Web: Geometric Analysis
by Rien van de Weygaert, Willem Schaap
Publisher: arXiv 2007
Number of pages: 129
Description:
The lecture notes describe the Delaunay Tessellation Field Estimator for Cosmic Web analysis. The high sensitivity of Voronoi/Delaunay tessellations to the local point distribution is used to obtain estimates of density and related quantities. The adaptive and minimum triangulation properties of Delaunay tessellations are utilized for interpolation to continuous volume-covering density and velocity fields.

This text covers the theory of cosmological perturbations, which describes the generation of inhomogeneities in the early universe and their evolution until the current time. The theory is applied to three classes of models of the early universe.

We review the question of primordial magnetic fields and consider the limits set on their strength by the observational data. The various mechanisms of pre-recombination magnetogenesis are presented and their advantages and shortcomings are debated.
