Cosmology: Galaxy Formation, Galaxy Formation: Numerical Simulations

Scientific paper

The formation of single galaxies in a cold dark matter cosmogony is investigated. The evolution of dark and baryonic matter and of the frequency-dependent spatially averaged radiation field is followed. Two extreme cases, the formation of an isolated field galaxy and the merging of two gas rich protospirals are considered as a model for galaxy formation in a cluster. The simulations start at a redshift of 25, when gas and dark matter are equally distributed. The isolated galaxy develops into an object which shows the main properties of spiral galaxies. Merging protospirals produce objects which can be interpreted as luminous ellipticals. Taken together, these simulations show, that under relatively simple assumptions about the important physical processes, the origin of the Hubble sequence can be well understood, if one takes into account initial conditions as predicted by cosmology.
