WebIn a hierarchical universe, galaxies form by a similarmerging and accretion process as clusters (Klypin et al. 1999). Over-merging on galactic scales is a necessary requirement, other-wise previous generations of the hierarchy would preclude the formation of disks. Observations suggest that overmerging has been nearly complete on galactic scales.
