Voids

Voids of Galaxies

Hume Feldman with Sergei Shandarin, we started looking into the substructure of voids, so here are a few animated views of voids and their distribution.
The simulations are done in a box of physical size L=256 Mpc/h based on a LCDM cosmology done by Katrin Heitmann and Salman Habib in LANL
Throughout this page Nc and Np refer to number of grid points (cells) and the number of particles in the simulation, respectively.
