The Carousel Lens II: Cosmological Constraints with GIGA-Lens
Felipe Urcelay, Xiaosheng Huang, William Sheu +28
The nature of dark matter and dark energy are among the central questions in cosmology. Strong gravitational lenses with multiple source planes provide a geometric probe of cosmolo…
DESI Strong Lens Foundry II: DESI Spectroscopy for Strong Lens Candidates
Xiaosheng Huang, Jose Carlos Inchausti, Christopher J. Storfer +59
We present the Dark Energy Spectroscopic Instrument (DESI) Strong Lensing Secondary Target Program. This is a spectroscopic follow-up program for strong gravitational lens candidat…
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 (…
DESI Strong Lens Foundry IV: Spectroscopic Confirmation of DESI Lens Candidates with VLT/MUSE
Emerald Lin, Ivonne Toro Bertolla, Aleksandar Cikota +6
We present integral field spectroscopic observations of 76 strong gravitational lens candidates identified with a residual neural network in the DESI Legacy Imaging Surveys, obtain…
An Agnostic Approach to Building Empirical Type Ia Supernova Light Curves: Evidence for Intrinsic Chromatic Flux Variation Using Nearby Supernova Factory Data
Jared Hand, A. G. Kim, G. Aldering +35
We present a new empirical Type Ia supernova (SN Ia) model with three chromatic flux variation templates: one phase dependent and two phase independent. No underlying dust extincti…
DESI Strong Lens Foundry I: HST Observations and Modeling with GIGA-Lens
X. Huang, S. Baltasar, N. Ratier-Werbin +56
We present the Dark Energy Spectroscopic Instrument (DESI) Strong Lens Foundry. We discovered new strong gravitational lens candidates in the DESI Legacy Imaging Survey…
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…
