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…
The Carousel Lens I: A Spectroscopic Survey of the Carousel Lens Field
Jackson H. O'Donnell, Demetrius Y. Williams, Tesla E. Jeltema +19
We present a spectroscopic survey of field galaxies and lensed sources in the vicinity of the strong lensing galaxy cluster known as the Carousel lens at z=0.49. Using both Gemini/…
Multi-band Reconstruction of Sixteen Gravitational Lens Systems using PISCO data
Huimin Qu, Daniel J. Ballard, Geraint F. Lewis +12
Next-generation surveys such as the Euclid survey, the Legacy Survey of Space and Time (LSST), and the China Space Station Telescope (CSST) survey are expected to discover ~10^5 ga…
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…
Achieving Gender Representation in Lead-Author Publications in the ASTRO3D Centre of Excellence
Kim-Vy H. Tran, Stuart Wyithe, Michelle Ding
We examine the publication rates of 400 research-focused members in the ASTRO3D Centre of Excellence by gender, project, and year from January 2018 to January 2024 (six years). Of…
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…
