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 …

In the past five years, deep imaging campaigns conducted with the Hubble Space
Telescope (HST) and ground-based observatories have delivered large samples of galaxies …

EIGER. I. A Large Sample of [O iii]-emitting Galaxies at 5.3 < z < 6.9 and Direct Evidence for
Local Reionization by Galaxies - IOPscience Skip to content IOP Science home Accessibility …

We discuss new Keck/MOSFIRE spectroscopic observations of four luminous galaxies at z≃
7–9 selected to have intense optical line emission by Roberts-Borsani et al. Previous follow …

We present new upper limits on the volume-weighted neutral hydrogen fraction,, at z∼ 5–6
derived from spectroscopy of bright quasars. The fraction of the Lyα and Lyβ forests that is …

We present UV luminosity functions of dropout galaxies at~– z 6 10 with the complete
Hubble Frontier Fields data. We obtain a catalog of∼ 450 dropout-galaxy candidates (350 …

Faint Lyα emitters become increasingly rarer toward the reionization epoch (z∼ 6–7).
However, observations from a very large (∼ 5 deg 2) Lyα narrow-band survey at z= 6.6 …

We present the SILVERRUSH program strategy and clustering properties investigated
with∼ 2000 Lyα emitters (LAEs) at z= 5.7 and 6.6 found in the early data of the Hyper …

We present the results from a spectroscopic survey using the MOSFIRE near-infrared
spectrograph on the 10 m Keck telescope to search for Lyα emission from candidate …

Cosmic reionization was the last major phase transition of hydrogen from neutral to highly
ionized in the intergalactic medium (IGM). Current observations show that the IGM is …
