Welcome!

Here we present a spectroscopic survey of Lyα emitters in the Extended Groth Strip (EGS) field, targeting the regime near the Epoch of Reionization. Using Keck/DEIMOS, we observed 947 high-𝒛 candidates with photometric redshifts from 3 < 𝒛_phot < 7 and down to an H-band (HST/WFC3 F160W) magnitude limit of < 27.5. Observations were taken over the course of 8 nights, with integration times ranging from 4 to 7.8 hours. Our survey secured 137 unique redshifts, 126 of which are Lyα emitters at 2.8 < 𝒛 < 6.5 with a mean redshift of 𝒛 = 4.3. We provide a comprehensive redshift catalog for our targets, as well as the reduced one- and two- dimensional spectra for each object.
