Void Dynamics [PDF]

, 2014
Cosmic voids are becoming key players in testing the physics of our Universe. Here we concentrate on the abundances and the dynamics of voids as these are among the best candidates to provide information on cosmological parameters.

The VIMOS Public Extragalactic Redshift Survey - Searching for Cosmic Voids [PDF]

, 2014
The characterisation of cosmic voids gives unique information about the large-scale distribution of galaxies, their evolution and the cosmological model. We identify and characterise cosmic voids in the VIMOS Public Extragalactic Redshift Survey (VIPERS)

Weak Gravitational Lensing by Voids [PDF]

, 1998
We consider the prospects for detecting weak gravitational lensing by underdensities (voids) in the large-scale matter distribution. We derive the basic expressions for magnification and distortion by spherical voids. Clustering of the background sources

Voids in the Large-Scale Structure [PDF]

, 1997
Voids are the most prominent feature of the LSS of the universe. Still, they have been generally ignored in quantitative analysis of it, essentially due to the lack of an objective tool to identify and quantify the voids. To overcome this, we present the

A hierarchy of voids: Much ado about nothing [PDF]

, 2003
We present a model for the distribution of void sizes and its evolution in the context of hierarchical scenarios of gravitational structure formation.

Statistical Geometry of Packing Defects of Lattice Chain Polymer from Enumeration and Sequential Monte Carlo Method [PDF]

, 2002
Voids exist in proteins as packing defects and are often associated with protein functions. We study the statistical geometry of voids in two-dimensional lattice chain polymers.

Sparse sampling, galaxy bias, and voids [PDF]

, 2014
To study the impact of sparsity and galaxy bias on void statistics, we use a single large-volume, high-resolution N-body simulation to compare voids in multiple levels of subsampled dark matter, halo populations, and mock galaxies from a Halo Occupation ...

Clumps into Voids [PDF]

, 2000
We consider a spherically symmetric distribution of dust and show that it is possible, under general physically reasonable conditions, for an overdensity to evolve to an underdensity (and vice versa).

Voids in cosmological simulations over cosmic time

, 2016
We study evolution of voids in cosmological simulations using a new method for tracing voids over cosmic time. The method is based on tracking watershed basins (contiguous regions around density minima) of well developed voids at low redshift, on a ...

The bias of cosmic voids in the presence of massive neutrinos [PDF]

, 2019
Cosmic voids offer an extraordinary opportunity to study the effects of massive neutrinos on cosmological scales. Because they are freely streaming, neutrinos can penetrate the interior of voids more easily than cold dark matter or baryons, which makes ...
