COOL-LAMPS. VII. Quantifying Strong-lens Scaling Relations with 177 Cluster-scale Strong Gravitational Lenses in DECaLS

Simon D. Mork, Michael D. Gladders, Gourav Khullar +27

We estimate the Einstein-radius-enclosed total mass for 177 cluster-scale strong gravitational lenses identified by the ChicagO Optically selected Lenses Located At the Margins of…

DESI Massive Post-Starburst Galaxies at $z \sim 1.2$ have compact structures and dense cores

Yunchong Zhang, David J. Setton, Sedona H. Price +33

Post-starburst galaxies (PSBs) are young quiescent galaxies that have recently experienced a rapid decrease in star formation, allowing us to probe the fast-quenching period of gal…

COOL-LAMPS VIII: Known wide-separation lensed quasars and their host galaxies reveal a lack of evolution in $M_{BH} / M_{⋆}$ since $z \sim 3$

Aidan P. Cloonan, Gourav Khullar, Kate A. Napier +36

Wide-separation lensed quasars (WSLQs) are a rare class of strongly lensed quasars, magnified by foreground massive galaxy clusters, with typically large magnifications of the mult…
