Recent observations with the JWST are yielding tantalizing hints of an early population of
massive, bright galaxies at z> 10, with Atacama Large Millimeter/submillimeter Array (ALMA) …

We present new upper limits on the volume-weighted neutral hydrogen fraction,, at z∼ 5–6
derived from spectroscopy of bright quasars. The fraction of the Lyα and Lyβ forests that is …

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 study the dust content of galaxies from z= 0 to z= 9 in semi-analytic models of galaxy
formation that include new recipes to track the production and destruction of dust. We …

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 …

We present the results of our ultra-deep Keck/DEIMOS spectroscopy of z-dropout galaxies in
the Subaru Deep Field and Great Observatories Origins Deep Survey's northern field. For 3 …

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 …

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 …

We present the final results from our ultra-deep spectroscopic campaign with FORS2 at the
ESO Very Large Telescope (VLT) for the confirmation of z≃ 7" z-band dropout" candidates …

We report deep ALMA observations complemented by associated Hubble Space Telescope
(HST) imaging for a luminous (m UV= 25) galaxy," Himiko," at a redshift of z= 6.595. The …
