**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.
