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 (…
Modified Gravity Constraints from the Full Shape Modeling of Clustering Measurements from DESI 2024
M. Ishak, J. Pan, R. Calderon +68
We present cosmological constraints on deviations from general relativity (GR) from the first-year of clustering observations from Dark Energy Spectroscopic Instrument (DESI) in co…
Mitigating Imaging Systematics for DESI 2024 Emission Line Galaxies and Beyond
A. J. Rosado-Marín, A. J. Ross, H. Seo +56
Emission Line Galaxies (ELGs) are one of the main tracers that the Dark Energy Spectroscopic Instrument (DESI) uses to probe the universe. However, they are afflicted by strong spu…
Discovering New Strong Gravitational Lenses in the DESI Legacy Imaging Surveys
X. Huang, C. Storfer, A. Gu +14
We have conducted a search for new strong gravitational lensing systems in the Dark Energy Spectroscopic Instrument Legacy Imaging Surveys' Data Release 8. We use deep residual neu…
One hundred SMUDGes in S-PLUS: ultra-diffuse galaxies flourish in the field
C. E. Barbosa, D. Zaritsky, R. Donnerstein +19
We present the first systematic study of the stellar populations of ultra-diffuse galaxies (UDGs) in the field, integrating the large area search and characterization of UDGs by th…
