Taming Additive Systematics via Redshift-Bin-Optimized Star-Galaxy Separation
Noah Weaverdyck, David Schlegel, Anand Raichoor +1
Contamination from stars in the galaxy samples of large-scale structure surveys can bias cosmological constraints if not tightly controlled. This is especially true for lens sample…
Testing CDM versus dynamical dark energy in one year: A DESI spectroscopic follow-up program for Rubin supernovae
Jannik Truong, Greg Aldering, Saul Perlmutter +2
Combined cosmological probes currently indicate that best-fit values in the parametrization of dynamical dark energy deviate from CDM by . In this work, we pre…
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…
A Novel Lensed Point Source Modeling Pipeline using GIGA-Lens with Application to SN Zwicky and SN iPTF16geu
Saul Baltasar, Nicolas Ratier-Werbin, Xiaosheng Huang +5
We introduce a novel modeling pipeline for strongly lensed point sources, using the GIGA-Lens framework, running on four A100 GPUs via the JAX platform. Using simulations, we demon…
DESI Strong Lens Foundry V: A Sample of HST-Observed Strong Lenses Modeled with GIGA-Lens
Xiaosheng Huang, David Alvarez-Garcia, Monica Ubeda +13
We present six galaxy-scale strong lenses with HST imaging modeled using GIGA-Lens. This is Paper V of the DESI Strong Lens Foundry series. These systems were discovered in the DES…
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…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: cosmological implications of the large-scale two-point correlation function
Ariel G. Sanchez, C. G. Scoccola, A. J. Ross +53
We obtain constraints on cosmological parameters from the spherically averaged redshift-space correlation function of the CMASS Data Release 9 (DR9) sample of the Baryonic Oscillat…
The Hubble Space Telescope Cluster Supernova Survey: VI. The Volumetric Type Ia Supernova Rate
K. Barbary, G. Aldering, R. Amanullah +40
We present a measurement of the volumetric Type Ia supernova (SN Ia) rate out to z ~ 1.6 from the Hubble Space Telescope Cluster Supernova Survey. In observations spanning 189 orbi…
