Detection of star formation in a near-pristine pocket of the Universe

Abstract We detect two high-confidence star-forming sources in the environment of a chemically near-pristine ([Fe/H] <−3.66 ; 2σ) Damped Lyα system (DLA) using Keck/KCWI. These are found via the hydrogen Lyα emission line at Δv = −1200 km s−1 (LAE1) and Δv = −200 km s−1 (LAE2) re...
