The Cosmic Web: Geometric Analysis
Rien van de Weygaert, Willem Schaap
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…
Delaunay recovery of cosmic density and velocity probes
W. E. Schaap, R. van de Weygaert
Optimally resolved one-dimensional density and velocity profiles through cosmological N-body simulations are constructed by means of the Voronoi-Delaunay tessellation reconstructio…
Reconstructing cosmological fields using tessellation methods
W. E. Schaap, R. van de Weygaert
Astronomical observations, physical experiments as well as computer simulations often involve discrete data sets supposed to represent a fair sample of an underlying smooth and con…
Tessellation Reconstruction Techniques
Rien van de Weygaert, Willem Schaap
The application of Voronoi and Delaunay tessellation based methods for reconstructing continuous fields from discretely sampled data sets is discussed. The succesfull operation as…
Continuous Fields and Discrete Samples: Reconstruction through Delaunay Tessellations
W. E. Schaap, R. van de Weygaert
Here we introduce the Delaunay Density Estimator Method. Its purpose is rendering a fully volume-covering reconstruction of a density field from a set of discrete data points sampl…
