Abstract The James Webb Space Telescope (JWST) is a large (6.6 m), cold (< 50 K), infrared
(IR)-optimized space observatory that will be launched early in the next decade into orbit …

▪ Abstract Galactic winds are the primary mechanism by which energy and metals are
recycled in galaxies and are deposited into the intergalactic medium. New observations are …

The protagonists of the last great phase transition of the universe—cosmic reionization—
remain elusive. Faint star-forming galaxies are leading candidates because they are found …

The high-redshift intergalactic medium (IGM) and the primeval galaxy population are rapidly
becoming the new frontier of extragalactic astronomy. We investigate the IGM properties and …

Axions are some of the best motivated particles beyond the Standard Model. We show how
the attractive self-interactions of dark matter (DM) axions over a broad range of masses, from …

Thomson optical depth τ measurements from Planck provide new insights into the
reionization of the universe. In pursuit of model-independent constraints on the properties of …

The 30 Doradus star-forming region in the Large Magellanic Cloud is a nearby analog of
large star-formation events in the distant universe. We determined the recent formation …

We address the origin of the robust bimodality observed in galaxy properties about a
characteristic stellar mass∼ 3× 1010 M⊙. Less massive galaxies tend to be ungrouped …

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< …

Gamma-ray bursts are the most luminous explosions in the Universe, and their origin and
mechanism are the focus of intense research and debate. More than three decades after …
