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 study of galaxy protoclusters is beginning to fill in unknown details of the important
phase of the assembly of clusters and cluster galaxies. This review describes the current …

Detections and non-detections of Lyman alpha (Lyα) emission from z> 6 galaxies (< 1 Gyr
after the big bang) can be used to measure the timeline of cosmic reionization. Of key …

We report the detection of extended Lyα haloes around 145 individual star-forming galaxies
at redshifts 3≤ z≤ 6 in the Hubble Ultra Deep Field observed with the Multi-Unit …

We report the detection of extended Lyα emission around individual star-forming galaxies at
redshifts z= 3− 6 in an ultradeep exposure of the Hubble Deep Field South obtained with …

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 …

Galaxies are surrounded by large reservoirs of gas, mostly hydrogen, that are fed by inflows
from the intergalactic medium and by outflows from galactic winds. Absorption-line …

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 …

ABSTRACT We report Hubble Space Telescope/Cosmic Origins Spectrograph observations
of the Lyα emission and interstellar absorption lines in a sample of 10 star-forming galaxies …

We perform joint modeling of the composite rest-frame far-UV and optical spectra of redshift
1.85≤ z≤ 3.49 star-forming galaxies to deduce key properties of the massive stars, ionized …
