Lyman Continuum escaping from in-situ formed stars in a tidal bridge at z = 3
T. E. Rivera-Thorsen, A. Le Reste, M. J. Hayes +11
We present an analysis of archival JWST NIRSpec IFS and HST imaging observations of the z = 3 Lyman-Continuum Emitter (LCE) candidate LACES104037. We show that a nearby galaxy, den…
Feedback and dynamical masses in high- galaxies: the advent of high-resolution NIRSpec spectroscopy
A. Saldana-Lopez, J. Chisholm, S. Gazagnes +11
Stellar feedback is an essential step in the baryon cycle of galaxies, but it remains unconstrained beyond Cosmic Noon. We study the ionized gas kinematics, dynamical mass and gas-…
The Sunburst Arc with JWST: II. Observations of an Eta Carinae Analog at
S. Choe, T. Emil Rivera-Thorsen, H. Dahle +11
"Godzilla" is a peculiar object within the gravitationally lensed Sunburst Arc at . Despite being very bright, it appears in only one of the twelve lensed images of the sou…
The Sunburst Arc with JWST: III. An Abundance of Direct Chemical Abundances
Brian Welch, T. Emil Rivera-Thorsen, Jane Rigby +11
We measure the gas-phase abundances of the elements He, N, O, Ne, S, Ar, and Fe in an individual H\textsc{ii} region known to be leaking Lyman-continuum photons in the Sunburst Arc…
The JWST-PRIMAL Legacy Survey. A JWST/NIRSpec reference sample for the physical properties and Lyman- absorption and emission of galaxies at
K. E. Heintz, G. B. Brammer, D. Watson +45
One of the surprising early findings with JWST has been the discovery of a strong "roll-over" or a softening of the absorption edge of Ly in a large number of galaxies at ($z\gt…
The Sunburst Arc with JWST: I. Detection of Wolf-Rayet stars injecting nitrogen into a low-metallicity, proto-globular cluster leaking ionizing photons
T. Emil Rivera-Thorsen, J. Chisholm, B. Welch +13
We report the detection of a population of Wolf-Rayet (WR) stars in the Sunburst Arc, a strongly gravitationally lensed galaxy at redshift . As the brightest known lensed g…
