The most metal-poor damped Ly[alpha] systems: insights into chemical evolution in the very metal-poor regime

ABSTRACT We present a high spectral resolution survey of the most metal-poor damped Lyα absorption systems (DLAs) aimed at probing the nature and nucleosynthesis of the earliest generations of stars. Our survey comprises 22 systems with iron abundance less than 1/100 solar; observations of seven of...
