The morphological evolution of galaxy clusters occurs during multiple high-speed collisions between galaxies. High-resolution numerical simulations show that during these interactions small disk galaxies are converted into dwarf elliptical or spheroidal galaxies. The debris arcs left after the encounters provide fuel for quasars in the sub-luminous host galaxies. The simulations suggest that these galaxy interactions are different from galaxy mergers.
