LEGGOS: Direct abundances of N, O, Ne, S, and Ar in five lensed galaxies at Cosmic Noon
Brian Welch, Gourav Khullar, Taylor A. Hutchison +14
We present direct chemical abundances in five strongly lensed galaxies at Cosmic Noon () using JWST/NIRSpec data from the LEGGOS survey. We measure g…

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 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…
