| Abstract: |
Evidence is presented that the damped Lyα absorption systems are the high-redshift (z>3) progenitors of galaxy disks. I discuss kinematic evidence that the damped Lyα systems are rotating disks. I also discuss implications of the lack of metal-poor damped Lyα systems with line width Δ v > 100 km/s. I then present new evidence stemming from correlations between element-abundance ratios and [Fe/H], which connects damped systems to the thick stellar disk of the Galaxy. I discuss the connections between damped Lyα systems and Lyman break galaxies, and how [CII] 158 μm emission from damped Lyα systems discriminates among competing theories of galaxy formation. |
