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 …

Ever deeper and wider look-back surveys have led to a fairly robust outline of the cosmic
star-formation history, which culminated around; this period is often nicknamed “cosmic …

We analyse the chemical properties of three z∼ 8 galaxies behind the galaxy cluster
SMACS J0723. 3-7327, observed as part of the Early Release Observations programme of …

We present rest-frame optical data of the compact z= 5.55 galaxy GS_3073 obtained using
the integral field spectroscopy mode of the Near-InfraRed Spectrograph on board the James …

We describe new JWST/NIRSpec observations of galaxies at z≳ 7 taken from the CEERS
survey. Previous observations of this area have revealed associations of Lyα emitters at …

We present emission-line ratios from a sample of 27 Lyman-break galaxies from z∼ 5.5− 9.5
with− 17.0< M 1500<− 20.4, measured from ultra-deep JWST/NIRSpec multi-object …

We investigate the evolution of galaxy gas-phase metallicity (O/H) over the range z= 0–3.3
using samples of∼ 300 galaxies at z∼ 2.3 and∼ 150 galaxies at z∼ 3.3 from the MOSDEF …

Context. LBQS 0302− 0019 is a blue quasar (QSO) at z∼ 3.3 that hosts powerful outflows
and resides in a complex environment consisting of an obscured active galactic nucleus …

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 …
