The evolution of the content of heavy elements in galaxies, the relative chemical
abundances, their spatial distribution, and how these scale with various galactic properties …

Abstract The GLASS-JWST Early Release Science (hereafter GLASS-JWST-ERS) Program
will obtain and make publicly available the deepest extragalactic data of the ERS campaign …

Recent observations of GN-z11 with JWST/NIRSpec revealed numerous oxygen, carbon,
nitrogen, and helium emission lines at z= 10.6. Using the measured line fluxes, we derive …

We report detections of the [O iii] λ4364 auroral emission line for 16 galaxies at z= 2.1–8.7,
measured from JWST/NIRSpec observations obtained as part of the Cosmic Evolution Early …

We present rest-frame optical emission-line flux ratio measurements for five z> 5 galaxies
observed by the James Webb Space Telescope Near-Infared Spectrograph (NIRSpec) in …

Quasar feedback in the form of powerful outflows is invoked as a key mechanism to quench
star formation in galaxies, although direct observational evidence is still scarce and debated …

We present a combined analysis of rest-frame far-UV (FUV; 1000–2000 Å) and rest-frame
optical (3600–7000 Å) composite spectra formed from very deep Keck/LRIS and …

We present initial results of a deep near-IR spectroscopic survey covering the 15 fields of the
Keck Baryonic Structure Survey using the recently commissioned MOSFIRE spectrometer on …

We present detections of [O iii] λ4363 and direct-method metallicities for star-forming
galaxies at z= 1.7–3.6. We combine new measurements from the MOSFIRE Deep Evolution …

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 …
