Most Strong Lensing Deflectors in the AGEL Survey Are in Group and Cluster Environments

William J. Gottemoller, Nandini Sahu, Rodrigo Cordova-Rosado +11

The environments of deflectors in strong lensing systems affect our ability to test cosmological models and constrain evolutionary properties of galaxies. Here we measure the defle…

Constraining Cosmology with Double-source-plane Strong Gravitational Lenses from the AGEL Survey

Duncan J. Bowden, Nandini Sahu, Anowar J. Shajib +17

Double-source-plane strong gravitational lenses (DSPLs), with two sources at different redshifts, are independent cosmological probes of the dark energy equation of state parameter…

Cosmography with the Double Source Plane Strong Gravitational Lens AGEL150745+052256

Nandini Sahu, Anowar J. Shajib, Kim-Vy Tran +14

Strong gravitational lenses with two background sources at widely separated redshifts are a powerful and independent probe of cosmological parameters. We can use these systems, kno…

Gravitational Lensing Reveals Cool Gas within 10-20 kpc around a Quiescent Galaxy

Tania M. Barone, Glenn G. Kacprzak, James W. Nightingale +12

While quiescent galaxies have comparable amounts of cool gas in their outer circumgalactic medium (CGM) compared to star-forming galaxies, they have significantly less interstellar…
