    Abstract

    Galaxies are gregarious, the vast majority living in groups, and a small fraction gathering in rich clusters of several thousand galaxies. Proto-clusters of galaxies begin to form in the over-densities of the young Universe, but only collapse and become gravitationally bound from 3 or 4 billion years after the Big-Bang. The fate of galaxies is strongly influenced by their environment.
