The existence of∼ 109M⊙ supermassive black holes (SMBHs) within the first billion years
of the Universe has stimulated numerous ideas for the prompt formation and rapid growth of …

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 …

We present new measurements of rest-UV luminosity functions and angular correlation
functions from 4,100,221 galaxies at z∼ 2–7 identified in the Subaru/Hyper Suprime-Cam …

Forthcoming observational facilities will make the exploration of the early universe routine,
likely probing large populations of galaxies at very low metallicities. It will therefore be …

We present our new Atacama Large Millimeter/Submillimeter Array (ALMA) observations
targeting [O iii] 88 μm,[C ii] 158 μm,[N ii] 122 μm, and dust-continuum emission for three …

We study the UV luminosity functions (LFs) at z∼ 4, 5, 6, and 7 based on the deep large-
area optical images taken by the Hyper Suprime-Cam (HSC) Subaru Strategic Program …

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 on the detection of the [C ii] 157.7 μ m emission from the Lyman break galaxy
(LBG) MACS0416_Y1 at z= 8.3113, by using the Atacama Large Millimeter/submillimeter …

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 …

The cosmic ionizing emissivity from star-forming galaxies has long been anchored to UV
luminosity functions. Here, we introduce an emissivity framework based on Lyα emitters …
