Identification and study of systems of galaxies in the Shapley supercluster

摘要: Based on the largest compilation of galaxies with redshift in region Shapley Supercluster (Proust et al. 2004, P2004), we identified 122 galaxy systems, 60 which are new systems. Using SuperCOSMOS catalogue, have assigned b j magnitudes to each our compilation. The sample systems was used estimate mass function range 10 13 to 10 15  ${M_{\odot}}\,h^{-1}$. We computed a lower value total this function. Using 15 mock catalogues derived mean that these kinds before comparing it obtained from real data.
