Hydrogen Lyman-α (Lyα) emission has been one of the major observational probes for the
high-redshift Universe since the first discoveries of high-z Lyα-emitting galaxies in the late …

The bulk of cosmic matter resides in a dilute reservoir that fills the space between galaxies,
the intergalactic medium (IGM). The history of this reservoir is intimately tied to the cosmic …

We present a new flexible Bayesian framework for directly inferring the fraction of neutral
hydrogen in the intergalactic medium (IGM) during the Epoch of Reionization (EoR, z∼ 6 …

The visibility of high-redshift Lyman-alpha emitting galaxies (LAEs) provides important
constraints on galaxy formation processes and the Epoch of Reionization (EoR). However …

We present the Lyα luminosity function (LF), clustering measurements, and Lyα line profiles
based on the largest sample to date of 207 Lyα emitters (LAEs) at z= 6.6 on the 1 deg 2 sky …

At the time of recombination, baryons and photons decoupled and the sound speed in the
baryonic fluid dropped from relativistic,∼ c/3, to the thermal velocities of the hydrogen …

The Epoch of Reionization (EoR) represents a milestone in the evolution of our Universe.
Star-forming galaxies that existed during the EoR likely emitted a significant fraction (~ 5 …

We present the results of our ultra-deep Keck/DEIMOS spectroscopy of z-dropout galaxies in
the Subaru Deep Field and Great Observatories Origins Deep Survey's northern field. For 3 …

We present the first results of a new Keck spectroscopic survey of UV faint Lyman break
galaxies in the redshift range 3< z< 7. Combined with earlier Keck and published European …

We present the Lyα luminosity functions (LFs) at z= 5.7 and 6.6 derived from a new large
sample of 1266 Lyα emitters (LAEs) identified in total areas of 14 and 21 deg2, respectively …
