Galaxy Clusters Selected via the Sunyaev-Zel'dovich Effect in 5 year data from the SPT-3G Main Survey
L. E. Bleem, M. Klein, K. Kornoelje +148
We report a new galaxy cluster catalog, selected using the thermal Sunyaev-Zel'dovich (SZ) effect, from 5 years of observations of the SPT-3G Main field. Drawn from arcminute-resol…
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…
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…
SLICE -- Combining Strong Lensing and X-ray in AC 114. Further Insights into the Merger Scenario
Marceau Limousin, Benjamin Beauchesne, Keren Sharon +14
AC114 is a historically significant galaxy cluster, being one of the first strong lensing clusters detected from the ground in the early 1990s, prior to the launch of the HST. Desp…
