Elemental abundances at early times: the nature of Damped Lyman-alpha systems
Mercedes Molla, Angeles Diaz, Federico Ferrini
Abstract
The distribution of element abundances with redshift in Damped Ly-alpha (DLA) systems can be adequately reproduced by the same model reproducing the halo and disk components of the Milky Way Galaxy at different galactocentric distances: DLA systems are well represented by normal spiral galaxies in their early evolutionary stages.
