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 …

We present emission-line measurements and physical interpretations for a sample of 117 [O
iii] emitting galaxies at z= 5.33–6.93, using the first deep JWST/NIRCam wide-field slitless …

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 …

We present the spectroscopic confirmation of a protocluster at z= 7.88 behind the galaxy
cluster Abell 2744 (hereafter A2744-z7p9OD). Using JWST NIRSpec, we find seven …

We study the ionizing photon production efficiency at the end of the Epoch of Reionization
(z∼ 5.4− 6.6) for a sample of 30 Ly α emitters. This is a crucial quantity to infer the ionizing …

We present observations with the Cosmic Origins Spectrograph (COS) onboard the Hubble
Space Telescope of five star-forming galaxies at redshifts in the range 0.2993–0.4317 and …

We report the detection of the Lyman continuum (LyC) radiation of the compact star-forming
galaxy (SFG) J1154+ 2443 observed with the Cosmic Origins Spectrograph (COS) onboard …

Using the Space Telescope Imaging Spectrograph, we have obtained ultraviolet spectra
from∼ 1200 to 2000 Å of known Lyman continuum (LyC) emitting galaxies at low redshift …

ABSTRACT The James Webb Space Telescope will allow to spectroscopically study an
unprecedented number of galaxies deep into the reionization era, notably by detecting [O iii] …

We present the discovery and analysis of J1316+ 2614 at z= 3.6130, a UV-bright star-
forming galaxy (M UV≃− 24.7) with large escape of Lyman continuum (LyC) radiation …
