We perform a ground-based near-infrared spectroscopic survey using the Keck/MOSFIRE spectrograph to target Ly\alpha emission at 7.0<z<8.2 from 61 galaxies to trace the ionization state of the intergalactic medium (IGM). We cover a total effective sky area of \sim10^\prime\times10^\prime in the Extended Groth Strip field of the Cosmic Assembly Near-infrared... Show more
