Galaxies: Formation, Lyman Alpha Systems

Scientific paper

Damped Lyman-α systems (DLAs) are very useful probes of high-redshift galaxy formation. They contain wealth of information, including gas and metal distribution in high-redshift galaxies and on the strength of feedback. Here we describe our research on the properties of DLAs using cosmological hydrodynamic simulations which include treatments of star formation and feedback, focusing on the effects of feedback on DLA cross-section and DLA distribution as a function of halo mass. We also suggest the correlation between DLAs and LBGs from DLA mean halo mass.
