CIV Absorption From Galaxies in the Process of Formation
Martin Haehnelt, Matthias Steinmetz, Michael Rauch
We investigate the heavy element QSO absorption systems caused by gas condensations at high redshift which evolve into galaxies with circular velocity of 100 to 200 km/s at the pre…
Simulating Galaxy Formation
Matthias Steinmetz
A review on numerical simulations of galaxy formation is given. Different numerical methods to solve collisionless and gas dynamical systems are outlined and one particular simulat…
Mergers and the Formation of Disk Galaxies in Hierarchically Clustering Universes
Matthias Steinmetz
New simulations are presented which investigate the formation of smaller groups of galaxies in a CDM like universe. The simulations follow the evolution of dark matter and gas and…
Photoionization Effects During Galaxy Formation
Matthias Steinmetz
SPH hydrodynamical simulations of the formation of galaxies are presented including the effects of an UV background radiation field. Based on a talk presented at the 17th Texas Sym…
