LEGGOS I: The JWST LEGGOS Survey -- LEnsing and Galaxy Growth: Observing Substructures -- Unpacks the Nature of Clumpy Star Formation and Quenching in Gravitationally Lensed Galaxies beyond Cosmic Noon
Gourav Khullar, Michael Florian, Matthew B. Bayliss +34
We present first results from the JWST LEGGOS Survey (LEnsing and Galaxy Growth: Observing Substructures), aimed at studying the physics of clumpy star formation and quenching in e…
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…
Tracing Structure: Shape and Centroid Deviations in 39 Strong Lensing Clusters as a Test of Cluster Formation Predictions
Raven Gassis, Matthew B. Bayliss, Keren Sharon +10
Strong lensing galaxy clusters provide a unique and powerful way to test simulation-derived structure predictions that follow from Cold Dark Matter (CDM) cosmology. Specific…
The Chandra Strong Lens Sample: Measuring the Dynamical States and Relaxation Fraction of a Sample of 28 Strong Lensing Selected Galaxy Clusters
Raven Gassis, Matthew B. Bayliss, Michael McDonald +10
We present the results of our dynamical state proxy measurements performed on 28 strong lensing galaxy clusters from the Sloan Giant Arcs Survey (SGAS). Using Chandra ACIS-I/S X-ra…
The Sunburst Arc with JWST. IV. The importance of interaction, turbulence, and feedback for Lyman-continuum escape
T. Emil Rivera-Thorsen, Brian Welch, Taylor Hutchison +13
At present, the best opportunity for detailed Lyman Continuum escape studies is in gravitationally lensed galaxies at z >~ 2. Only one such galaxy currently exists in the literatur…
Cool dark gas in Cygnus X: The first large-scale mapping of low-frequency carbon recombination lines
Kimberly L. Emig, Pedro Salas, Loren D. Anderson +14
Understanding the transition from atomic gas to molecular gas is critical to explain the formation and evolution of molecular clouds. However, the gas phases involved, cold HI and…
Connecting Lyman- and ionizing photon escape in the Sunburst Arc
M. Riley Owens, Keunho J. Kim, Matthew B. Bayliss +17
We investigate the Lyman- (Ly) and Lyman continuum (LyC) properties of the Sunburst Arc, a gravitationally lensed galaxy with a multiply-imaged, compact region leaki…
COOL-LAMPS VIII: Known wide-separation lensed quasars and their host galaxies reveal a lack of evolution in since
Aidan P. Cloonan, Gourav Khullar, Kate A. Napier +36
Wide-separation lensed quasars (WSLQs) are a rare class of strongly lensed quasars, magnified by foreground massive galaxy clusters, with typically large magnifications of the mult…
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 Sunburst Arc with JWST: I. Detection of Wolf-Rayet stars injecting nitrogen into a low-metallicity, proto-globular cluster leaking ionizing photons
