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 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 …

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 …

We present a detailed analysis of the rest-frame optical emission line ratios for three
spectroscopically confirmed galaxies at z> 7.5. The galaxies were identified in the James …

We present a new flexible Bayesian framework for directly inferring the fraction of neutral
hydrogen in the intergalactic medium (IGM) during the Epoch of Reionization (EoR, z∼ 6 …

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 …

Lyα emission from galaxies can be utilized to characterize the ionization state in the
intergalactic medium (IGM). We report our search for Lyα emission at z> 7 using a …

Abstract The Early Release Observations (EROs) of JWST beautifully demonstrate the
promise of JWST in characterizing the universe at Cosmic Dawn. We analyze the Near …

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 …
