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 Search for Binary Black Hole Mergers in LIGO O1-O3 Data with Convolutional Neural Networks
Ethan Silver, Plamen Krastev, Edo Berger
Since the first detection of gravitational waves in 2015 by LIGO from the binary black hole merger GW150914, gravitational-wave astronomy has developed significantly, with over 200…
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…
ML-Driven Strong Lens Discoveries: Down to and
Ethan Silver, R. Wang, Xiaosheng Huang +3
We present results on extending the strong lens discovery space down to much smaller Einstein radii () and much lower halo mass ($M_\mathrm{halo}<10^{11}M_\odot…
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…
