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…
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…
The Carousel Lens I: A Spectroscopic Survey of the Carousel Lens Field
Jackson H. O'Donnell, Demetrius Y. Williams, Tesla E. Jeltema +18
We present a spectroscopic survey of field galaxies and lensed sources in the vicinity of the strong lensing galaxy cluster known as the Carousel lens at z=0.49. Using both Gemini/…
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…
Optical and near-infrared nebular-phase spectroscopy of SN 2024ggi: constraints on the structure of the inner ejecta, progenitor mass, and dust
Emilio Hueichapán, Régis Cartier, Jose L. Prieto +7
We present optical and near-infrared (NIR) spectroscopic observations of the nearby Type II supernova SN\,2024ggi from 250 and 581 days after the explosion. Comparing the evolution…
The discovery and characterization of Earth-crossing asteroid 2024 YR
Bryce T. Bolin, Josef Hanuš, Larry Denneau +9
We describe observations and physical characteristics of Earth-crossing asteroid 2024 YR, discovered on 2024 December 27 by the Asteroid Terrestrial-impact Last Alert System. T…
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…
Unveiling the nature of SN 2022jli: The first double-peaked stripped-envelope supernova showing periodic undulations and dust emission at late times
Régis Cartier, Carlos Contreras, Maximilian Stritzinger +6
We present optical and infrared observations from maximum light until around +800 days of supernova (SN) 2022jli, a peculiar stripped-envelope (SE) SN showing two maxima, each one…
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…
The optimisation of short-term scheduling of science observations at Paranal observatory (VLT and ELT)
Joseph P. Anderson, Elyar Sedaghati, Aleksandar Cikota +4
The efficiency of science observation Short-Term Scheduling (STS) can be defined as being a function of how many highly ranked observations are completed per unit time. Current STS…
