The HETDEX Survey: Probing Neutral Hydrogen in the Circumgalactic Medium of ∼88,000 Lyα Emitters

The HETDEX Survey: Probing Neutral Hydrogen in the Circumgalactic Medium of ∼88,000 Lyα Emitters

We explore the neutral hydrogen (H i ) gas around 1.9 <  z  < 3.5 Lyman alpha emitters (LAEs) from the Hobby–Eberly Telescope Dark Energy Experiment using faint Ly α absorption. This absorption is the result of H i in the halo of the LAE scattering Ly α photons from the integrated light of bac...
