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 …

Hydrogen Lyman-α (Lyα) emission has been one of the major observational probes for the
high-redshift Universe since the first discoveries of high-z Lyα-emitting galaxies in the late …

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 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 …

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 …

Most of the hydrogen in the intergalactic medium (IGM) was rapidly ionized at high redshifts.
While observations have established that reionization occurred, observational constraints on …

Galaxy formation is at the heart of our understanding of cosmic evolution. Although there is a
consensus that galaxies emerged from the expanding matter background by gravitational …

The escape fraction of Lyman-continuum (LyC) photons (f esc) is a key parameter for
determining the sources of cosmic reionization at z≥ 6. At these redshifts, owing to the …

The relationships between stellar mass, gas-phase metallicity and star-formation rate (ie the
mass–metallicity, MZR, and the fundamental metallicity relation, FMR) in the local Universe …

The ionizing photon escape fraction [Lyman continuum (LyC) f esc] of star-forming galaxies
is the single greatest unknown in the reionization budget. Stochastic sightline effects prohibit …
