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 …

We describe new JWST/NIRSpec observations of galaxies at z≳ 7 taken from the CEERS
survey. Previous observations of this area have revealed associations of Lyα emitters at …

We present a new flexible Bayesian framework for directly inferring the fraction of neutral
hydrogen in the intergalactic medium (IGM) during the Epoch of Reionization (EoR, z∼ 6 …

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 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 present new ALMA observations and physical properties of a Lyman break galaxy at z=
7.15. Our target, B14-65666, has a bright ultra-violet (UV) absolute magnitude, M UV≈ …

We develop a new method to determine the distance between a high-redshift galaxy and a
foreground screen of atomic hydrogen. In a partially neutral universe, and assuming …

The redshift-dependent fraction of color-selected galaxies revealing Lyman alpha (Lyα)
emission, x Lyα has become the most valuable constraint on the evolving neutrality of the …

We present a systematic study for ionization state of inter-stellar medium in galaxies at z= 0–
with∼ 140 000 Sloan Digital Sky Survey (SDSS) galaxies and 108 intermediate-to high …
