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 …

Galaxy formation is at the heart of our understanding of cosmic evolution. Although there is a
consensus that galaxies emerged from the expanding matter background by gravitational …

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 …

Intermediate-mass black holes (IMBHs), with masses in the range 1 0 0–1 0 6 M⊙, are the
link between stellar-mass BHs and supermassive BHs (SMBHs). They are thought to be the …

The relationship between stellar populations and the ionizing flux with which they irradiate
their surroundings has profound implications for the evolution of the intergalactic medium …

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 report the discovery of Lyman-alpha emission (Lyα) in the bright galaxy EGSY-
2008532660 (hereafter EGSY8p7) using the Multi-Object Spectrometer For Infra-Red …

In recent years, the discovery of massive quasars at has provided a striking challenge to our
understanding of the origin and growth of supermassive black holes in the early Universe …

We study very high rate, spherically symmetric accretion flows on to massive black holes
(BHs; 102≲ M BH≲ 106 M⊙) embedded in dense metal-poor clouds, performing one …

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 …
