Modeling cosmic void statistics
Nico Hamaus, P. M. Sutter, Benjamin D. Wandelt
Understanding the internal structure and spatial distribution of cosmic voids is crucial when considering them as probes of cosmology. We present recent advances in modeling void d…
Large-Scale Clustering of Cosmic Voids
Kwan Chuen Chan, Nico Hamaus, Vincent Desjacques
We study the clustering of voids using -body simulations and simple theoretical models. The excursion-set formalism describes fairly well the abundance of voids identified with…
Testing cosmic geometry without dynamic distortions using voids
Nico Hamaus, P. M. Sutter, Guilhem Lavaux +1
We propose a novel technique to probe the expansion history of the Universe based on the clustering statistics of cosmic voids. In particular, we compute their two-point statistics…
VIDE: The Void IDentification and Examination toolkit
P. M. Sutter, Guilhem Lavaux, Nico Hamaus +7
We present VIDE, the Void IDentification and Examination toolkit, an open-source Python/C++ code for finding cosmic voids in galaxy redshift surveys and N-body simulations, charact…
The life and death of cosmic voids
P. M. Sutter, Pascal Elahi, Bridget Falck +5
We investigate the formation, growth, merger history, movement, and destruction of cosmic voids detected via the watershed transform code VIDE in a cosmological N-body dark matter…
Universal Density Profile for Cosmic Voids
Nico Hamaus, P. M. Sutter, Benjamin D. Wandelt
We present a simple empirical function for the average density profile of cosmic voids, identified via the watershed technique in CDM N-body simulations. This function is univer…
