Gaseous Galactic Halos and QSO Absorption Line Systems
Abstract
Description
Recent observations have shown that (some) metal line absorption systems in QSO spectra arise from gas in galactic halos with radii much larger than the optical radii of galaxies. We show that the observed galaxy-absorber connections are natural results of galaxy formation in hierarchical cosmogonies, where galaxies form from gas cooling and condensation in dark matter halos.
