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…

LEGGOS II: A Strong Lens Model and Source-Plane Projection of the Clumpy Star-Forming Galaxy SGASJ111020.0+645950.8 at z=2.48

Pedram Abedi, Keren Sharon, Taylor A. Hutchison +18

Strong gravitational lensing by galaxy clusters combined with the resolution of JWST enables studies of star formation on ~10-100 pc scales in galaxies at z~2-4. As part of the LEn…

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…

SPT-CL J0417-4748: A Deep Chandra Study of a Relaxed Galaxy Cluster Without Central Star Formation

Taweewat Somboonpanyakul, Adam B. Mantz, Steven W. Allen +7

We present an in-depth Chandra X-ray analysis of the galaxy cluster SPT-CL J04174748 (hereafter SPT J0417), at z = 0.58, with a focus on its thermodynamic properties and the app…

Using gravitational lensing to probe for bright quintessential galaxies in the Epoch of Reionization

Joshua Roberson, Matthew B. Bayliss, M. D. Gladders +6

Understanding the properties of the first generation of galaxies is an ongoing challenge in observational astrophysics. While advances in deep field observation have led to the ide…

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…
