Abstract

We investigate the physical properties of the progenitors of today living Milky Way-like galaxies that are visible as Damped Lyα Absorption systems and Lyα Emitters at higher redshifts (z ≍ 2.3,5.7). To this aim we use a statistical merger-tree approach that follows the formation of the Galaxy and its dwarf satellites in a cosmological context, tracing the chemical evolution and stellar population history of the progenitor halos. The model accounts for the properties of the most metal-poor stars and local dwarf galaxies, providing insights on the early cosmic star-formation. Fruitful links between Galactic Archaeology and more distant galaxies are presented.
