Evolution of a cluster of 50 Galaxies simulation

This movie shows the evolution of a cluster of fifty galaxies. The white particles are the luminous cores of the galaxies; the red particles are the dark matter halos of the galaxies; and the blue particles form the dark matter cluster background. The duration of the simulation covers 16 gigayears (billion years). The field of view is roughly a megaparsec (3.26 million lightyears). Due to dynamical friction and galatic interactions, the largest galaxies fall to the center of the cluster to form a dominant central galaxy through merging.
