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…
LEGGOS III: Mapping Star Formation and Dust in Gravitationally Lensed Galaxies with , a UMAP and Clustering Framework
Alex Ross, Gourav Khullar, Taylor Hutchison +10
Strong gravitational lensing combined with JWST's spatio-spectral resolution enables resolved studies of star-forming regions in 2-4 galaxies, but identifying and character…
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…
