The LEDA galaxy distribution: I. Maps of the Local Universe

Abstract

In order to investigate the properties of large-scale structures of galaxies in the universe, we present an analysis of their spatial distribution at z$<$0.033. We used the LEDA extragalactic database containing over 1 million of galaxies covering the all-sky and the SDSS data included in the public release DR1, yielding to a sample of around 134,000 galaxies having a measured redshift in two survey areas representing 690 sq. degrees. The results of the study are 2D, 3D maps and magnitude number counts of galaxies, drawn from B-band samples. Movies and high resolution figures are available on http://www-obs.univ-lyon1.fr/cosmologie/helene.html
