摘要：

The relation between high redshift galaxies and QSO absorption systems is discussed in the context of hierarchical galaxy formation. The study is based on hydrodynamical simulations which include star formation, feedback due to supernovae and chemical enrichment. It is shown that present day L* galaxies typically have several progenitors at z approximate to 3 spread over a few hundred kpc. These progenitors have velocity dispersions, luminosities and colors comparable to U-dropout galaxies at z approximate to 3. They are closely associated with damped Ly alpha and Ly-limit systems.
