HST imaging, pipeline modeling, and time-delay predictions of 2 triply-imaged and 15 quadruply-imaged lensed quasars
William Sheu, Tommaso Treu, Adriano Agnello +10
The Hubble tension remains a significant challenge in modern cosmology, exhibiting a discrepancy between early-Universe cosmic microwave background measurements and local distance…
XShooter DESI Lens Program: Sample characterization
Eric Jullo, Christophe Boghossian, Luderic Chapel +6
Large imaging surveys in cosmology are detecting orders of magnitude more lens systems than known so far. This unprecedented dataset will lead to robust constraints on cosmology an…
Finding Strongly Lensed Supernovae from Blended Light Curves
Sangwoo Park, Arman Shafieloo, Alex G. Kim +2
We present a model-independent, photometry-only framework for identifying strongly lensed supernovae when multiple images are unresolved and blended into a single point source. Bui…
A New Way to Discover Strong Gravitational Lenses: Pair-wise Spectroscopic Search from DESI DR1
Yuan-Ming Hsu, Xiaosheng Huang, Christopher J. Storfer +47
We present a new method to search for strong gravitational lensing systems by pairing spectra that are close together on the sky in a spectroscopic survey. We visually inspect 26,6…
DESI Strong Lens Foundry III: Keck Spectroscopy for Strong Lenses Discovered Using Residual Neural Networks
Shrihan Agarwal, Xiaosheng Huang, William Sheu +49
We present spectroscopic data of strong lenses and their source galaxies using the Keck Near-Infrared Echellette Spectrometer (NIRES) and the Dark Energy Spectroscopic Instrument (…
Confirming lensed-quasar candidates with DESI and P200 spectroscopy I. 14 lensed quasars and 8 lensed galaxies
Zizhao He, Qihang Chen, Xiaosheng Huang +3
Lensed quasars are powerful probes of cosmology, the co-evolution of supermassive black holes and their host galaxies, and the distribution of dark matter. We cross-match 1,724 pre…
The Roman View of Strong Gravitational Lenses
Bryce Wedig, Tansu Daylan, Simon Birrer +13
Galaxy-galaxy strong gravitational lenses can constrain dark matter models and the Lambda Cold Dark Matter cosmological paradigm at sub-galactic scales. Currently, there is a deart…
Gravitational Lenses in UNIONS and Euclid (GLUE) I: A Search for Strong Gravitational Lenses in UNIONS with Subaru, CFHT, and Pan-STARRS Data
Christopher J. Storfer, Eugene A. Magnier, Xiaosheng Huang +11
We present the results of our pipeline for discovering strong gravitational lenses in the ongoing Ultraviolet Near-Infrared Optical Northern Survey (UNIONS). We successfully train…
The AGEL Survey Data Release 2: A Gravitational Lens Sample for Galaxy Evolution and Cosmology
Tania M. Barone, Keerthi Vasan G. C., Kim-Vy Tran +31
The ASTRO 3D Galaxy Evolution with Lenses (AGEL) Survey is an ongoing effort to spectroscopically confirm a diverse sample of gravitational lenses with high spatial resolution imag…
Detection of Unresolved Strongly Lensed Supernovae with 7-Dimensional Telescope
Elahe Khalouei, Arman Shafieloo, Alex G. Kim +6
Gravitationally lensed supernovae (glSNe) are a powerful tool for exploring the realms of astronomy and cosmology. Time-delay measurements and lens modeling of glSNe can provide a…
The Carousel Lens: A Well-Modeled Strong Lens with Multiple Lensed Sources
William Sheu, Aleksandar Cikota, Xiaosheng Huang +12
Over the past few years alone, the lensing community has discovered thousands of strong lens candidates, and spectroscopically confirmed hundreds of them. In this time of abundance…
A Targeted Search for Variable Gravitationally Lensed Quasars
William Sheu, Xiaosheng Huang, Aleksandar Cikota +4
We present a pipeline to identify photometric variability within strong gravitationally lensing candidates, in the DESI Legacy Imaging Surveys. In our first paper (Sheu et al. 2023…
Union Through UNITY: Cosmology with 2,000 SNe Using a Unified Bayesian Framework
David Rubin, Greg Aldering, Marc Betoule +8
Type Ia supernovae (SNe Ia) were instrumental in establishing the acceleration of the universe's expansion. By virtue of their combination of distance reach, precision, and prevale…
