Tidal Torques and Galactic Warps
Jeremy Bailin, Matthias Steinmetz
(Abridged) We investigate how galactic disks react to external tidal torques. We calculate the strength and radial dependence of torques on disks that arise from a misalignment bet…
Galaxy Formation Now and Then
Matthias Steinmetz
I review the current state of our understanding of the galaxy formation and evolution process from the modeler's perspective. With the advent of the cold dark matter model and the…
Using VLBI Data to Investigate the Galaxy Structure in the Gravitationally Lensed System B1422+231
M. Bradac, P. Schneider, M. Steinmetz +3
Gravitationally lensed systems with multiply imaged quasars are an excellent tool for studying the properties of distant galaxies. In particular, they provide the most accurate mas…
Numerical studies of galaxy formation using special purpose hardware
Matthias Steinmetz
I review recent progress in numerically simulating the formation and evolution of galaxies in hierarchically clustering universes. Special emphasis is given to results based on hig…
The Cosmological Origin of Disk Galaxy Scaling Laws
Matthias Steinmetz, Julio F. Navarro
We discuss possible origins of scaling laws relating structural properties of disk galaxies within the context of hierarchically clustering theories of galaxy formation. Using gasd…
Model Predictions for Clustering and Morphologies at HDF depths
Matthias Steinmetz
The current status of numerical simulations of the formation of galaxies is reviewed. Success and failure of modeling galaxies at low and high redshift is demonstrated using a vari…
