Quasars at cosmic dawn provide powerful probes of the formation and growth of the earliest
supermassive black holes (SMBHs) in the Universe, their connections to galaxy and …

Neutral-atomic and molecular outflows are a common occurrence in galaxies, near and far.
They operate over the full extent of their galaxy hosts, from the innermost regions of galactic …

Spectroscopy with the James Webb Space Telescope has opened the possibility of
identifying moderate-luminosity active galactic nuclei (AGNs) in the early Universe, at and …

We report the results of near-infrared spectroscopic observations of 37 quasars in the
redshift range 6.3< z≤ 7.64, including 32 quasars at z> 6.5, forming the largest quasar near …

We measure the UV-continuum slope β for over 4000 high-redshift galaxies over a wide
range of redshifts z∼ 4–8 and luminosities from the HST HUDF/XDF, HUDF09-1, HUDF09 …

We study the evolution of the ionization state of the intergalactic medium (IGM) at the end of
the reionization epoch using moderate-resolution spectra of a sample of 19 quasars at 5.74< …

ABSTRACT We present Atacama Large Millimeter/submillimeter Array (ALMA) observations
of the [C ii] 158 μm fine structure line and dust continuum emission from the host galaxies of …

ABSTRACT Ultra-deep Advanced Camera for Surveys (ACS) and WFC3/IR HUDF+
HUDF09 data, along with the wide-area GOODS+ ERS+ CANDELS data over the CDF-S …

We combine a large set of quasar luminosity function (QLF) measurements from the rest-
frame optical, soft and hard X-ray, and near-and mid-IR bands to determine the bolometric …

Gamma-ray bursts (GRBs) serve as powerful probes of the early universe, with their
luminous afterglows revealing the locations and physical properties of star-forming galaxies …
