Filaments of galaxies and Voronoi diagrams

Lorenzo Zaninetti
Published Online: 2018-12-31 | DOI: https://doi.org/10.1515/astro-2018-0040


The intersections between a spherical shell and the faces of Voronoi polyhedrons are numerically evaluated. The nodes of these intersections are the points that share the same distances from three nuclei. The nodes are assumed to be the places where we will find clusters of galaxies. The cosmological environment is given by the coupling between the number of galaxies as function of the redshift and the LCDM cosmology.

Keywords: galaxy groups; clusters; and superclusters; large scale structure of the Universe Cosmology
