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…

JWST Catches a Strongly Gravitationally Lensed AGN In Transition from Type II to Type I

Michael K Florian, Michael D Gladders, Gourav Khullar +10

JWST has enabled the discovery of a statistical sample of obscured (type II) active galactic nuclei (AGN) at cosmic noon. Studies comparing those type II AGN with type I AGN at tha…

COOL-LAMPS IX: A Rare Duo of Quasars Each Lensed by a Single Massive Galaxy Cluster

Erik Solhaug, Michael D. Gladders, Andi M. Kisare +20

Wide-separation lensed quasars (WSLQs) are rare systems that arise from the chance alignment of two objects: a galaxy cluster and a background quasar. After two decades, only seven…

A Kiloparsec-Scale Stellar Cavity in the Center of Abell402-BCG May be Caused by Dynamic Interactions with an Ultramassive Black Hole

Michael McDonald, Gourav Khullar, David Lagattuta +18

We present new observations from JWST NIRCam that reveal a striking kpc-wide cavity in the stellar distribution of the central galaxy in the cluster Abell402. Supporting data from…

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…
