A new method for accurate velocity statistics estimation
Francis Bernardeau, Rien van de Weygaert
We introduce two new methods to obtain reliable velocity field statistics from N-body simulations, or indeed from any general density and velocity fluctuation field sampled by disc…
Constraining Peaks in Gaussian Primordial Density Fields: an Application of the Hoffman-Ribak Method
Rien van de Weygaert, Edmund Bertschinger
We develop an algorithm for setting up initial Gaussian random density and velocity fields containing one or more peaks or dips, in an arbitrary cosmological scenario. The intentio…
The Two--Point Correlation Function and the Size of Voids
Dalia S. Goldwirth, Luiz Nicolaci da Costa, Rien Van de Weygaert
Under the assumption of a void-filled Universe we investigate if the characteristic scale of voids can be determined from existing surveys. We use the Voronoi tessellation to creat…
