The observable characteristics and subsequent evolution of young stellar populations is
dominated by their massive stars. As our understanding of those massive stars and the …

Observations of the high-redshift Universe with the 21cm hyperfine line of neutral hydrogen
promise to open an entirely new window onto the early phases of cosmic structure formation …

The origins of Lyman continuum (LyC) photons responsible for the reionization of the
universe are as of yet unknown and highly contested. Detecting LyC photons from the Epoch …

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 …

We report the discovery of a remarkable Lyα emitting galaxy at z= 7.2782, JADES-GS+
53.16746− 27.7720 (shortened to JADES-GS-z7-LA), with rest-frame equivalent width, EW 0 …

We present an updated model of the cosmic ionizing background from the UV to the X-rays.
Relative to our previous model, the new model provides a better match to a large number of …

Using ultraviolet absorption lines, we analyze the systematic properties of the warm ionized
phase of starburst-driven winds in a sample of 39 low-redshift objects that spans broad …

We present a comprehensive study of the physical properties of∼ 105 galaxies with
measurable star formation in the Sloan Digital Sky Survey (SDSS). By comparing physical …

▪ 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 …

We present the results of a systematic study of the rest-frame UV spectroscopic properties of
Lyman break galaxies (LBGs). The database of almost 1000 LBG spectra proves useful for …
