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…

Chandra detects low-luminosity AGN with in nearby (), dwarf and star-forming galaxies

Mainak Singha, Julissa Sarmiento, Sangeeta Malhotra +8

We searched the Chandra and XMM archives for observations of 900 green pea galaxies to find AGN signatures. Green peas are low-mass galaxies with prominent emission lines, similar…
