Abstract:
Based on the largest compilation of galaxies with redshift in the
region of the Shapley Supercluster (Proust et al., 2004 in prep.,
2006A&A...447..133P 2006A&A...447..133P), we identified 122 galaxy systems, 60 of which
are new systems. Using the SuperCOSMOS catalogue, we have assigned
bj magnitudes to each galaxy in our compilation. The sample of
galaxy systems was used to estimate the mass function of systems in
the range 1013 to 1015M_☉/h-1. We computed a lower value to
the total mass in the region of the Shapley Supercluster with this
mass function. Using 15 mock catalogues we derived the mean mass that
these kinds of systems have before comparing it with that obtained
from the real data.
