The first observations of the James Webb Space Telescope (JWST) have revolutionized our
understanding of the Universe by identifying galaxies at redshift z≈ 13 (refs.,–). In addition …

Reionization is thought to be driven by faint star-forming galaxies, but characterizing this
population has long remained very challenging. Here, we utilize deep nine-band JADES …

Finding the emergence of the first metals in the early Universe and identifying their origin are
some of the most important goals of modern astrophysics. We present deep JWST/NIRSpec …

We present an analysis of JWST Lyα spectroscopy of z≳ 6.5 galaxies, using observations in
the public archive covering galaxies in four independent fields: Great Observatories Origins …

JWST is uncovering the properties of ever-increasing numbers of galaxies at z> 6, during the
epoch of reionization. Connecting these observed populations to the process of reionization …

We describe JWST/NIRSpec prism measurements of Ly α emission in z≳ 5 galaxies. We
identify Ly α detections in 10 out of 69 galaxies with robust rest-optical emission-line redshift …

We present a new suite of late-end reionization simulations performed with aton-he, a
revised version of the GPU-based radiative transfer code aton that includes helium. The …

Extreme emission line galaxies (EELGs) exhibit large equivalent widths (EW) in their rest-
optical emission lines ([O iii] or H rest-frame EW Å) which can be tied to a recent upturn in …

Context. One of the surprising early findings with JWST has been the discovery of a strong
“roll-over” or a softening of the absorption edge of Lyα in a large number of galaxies at z≳ 6 …

The attenuation of Lyα photons by neutral hydrogen in the intergalactic medium (IGM) at z≳
5 continues to be a powerful probe for studying the epoch of reionization. Given a framework …
