Parity-odd Four-Point Correlation Function from DESI Data Release 1 Luminous Red Galaxy Sample
J. Hou, R. N. Cahn, J. Aguilar +33
The parity-odd four-point function provides a unique probe of fundamental symmetries and potential new physics in the large-scale structure of the Universe. We present measurements…
Measurements of quasar proximity zones with the Ly forest of DESI Y1 quasars
Ryuichiro Hada, Paul Martini, David H. Weinberg +41
The intergalactic medium (IGM) around quasars is shaped by their dense environments and by their excess ionizing radiation, forming a "quasar proximity zone" whose size and anisotr…
The DESI Single Fiber Lens Search. I. Four Thousand Spectroscopically Selected Galaxy-Galaxy Gravitational Lens Candidates
Juliana S. M. Karp, David J. Schlegel, Xiaosheng Huang +47
We present 4,110 strong gravitational lens candidates, 3,887 of which are new discoveries, selected from a sample of 5,837,154 luminous red galaxies (LRGs) observed with the Dark E…
The Multi-Phase Circumgalactic Medium of DESI Emission-Line Galaxies at z~1.5
Ting-Wen Lan, J. Xavier Prochaska, J. Aguilar +39
We study the multi-phase circumgalactic medium (CGM) of emission line galaxies (ELGs) at , traced by MgII, and CIV, …
The Draco Dwarf Spheroidal Galaxy in the First Year of DESI Data
J. Ding, C. Rockosi, Ting S. Li +40
We investigate the spatial distribution, kinematics, and metallicity of stars in the Draco dwarf spheroidal galaxy using data from the Dark Energy Spectroscopic Instrument (DESI).…
Constraining GREA, an alternative theory accounting for the present cosmic acceleration
R. Calderon, J. Garcia-Bellido, B. Vos-Gines +34
The origin of the Universe's late-time accelerated expansion remains unknown. The General Relativistic Entropic Acceleration (GREA) theory offers a compelling alternative to CDM…
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…
The Compilation and Validation of the Spectroscopic Redshift Catalogs for the DESI-COSMOS and DESI-XMMLSS Fields
J. Ratajczak, K. S. Dawson, N. Weaverdyck +74
Over several dedicated programs that include targets beyond the main cosmological samples, the Dark Energy Spectroscopic Instrument (DESI) collected spectra for 304,970 unique obje…
The mass of the Milky Way from outer halo stars measured by DESI DR1
Gustavo E. Medina, Ting S. Li, Gwendolyn M. Eadie +50
As a benchmark for galaxy evolution and dark matter studies, the total mass of the Milky Way is a parameter of cosmological significance, and its value at large radii from the Gala…
Beyond Traditional Diagnostics: Identifying Active Galactic Nuclei with Spectral Energy Distribution Fitting in DESI Data
M. Siudek, M. Mezcua, C. Circosta +36
Active galactic nuclei (AGN) are typically identified through their distinctive X-ray or radio emissions, mid-infrared (MIR) colors, or emission lines. However, each method capture…
The Backup Program of the Dark Energy Spectroscopic Instrument's Milky Way Survey
Arjun Dey, Sergey E. Koposov, Joan R. Najita +66
The Milky Way Backup Program (MWBP), a survey currently underway with the Dark Energy Spectroscopic Instrument (DESI) on the Nicholas U. Mayall 4-m Telescope, works at the margins…
DESI Data Release 1: Stellar Catalogue
Sergey E. Koposov, Ting S. Li, C. Allende Prieto +65
In this paper we present the stellar Value-Added Catalogue (VAC) based on the DESI Data Release 1. This VAC contains stellar parameter, abundance and radial velocity measurements f…
The DESI Y1 RR Lyrae catalog II: The metallicity dependency of pulsational properties, the shape of the RR Lyrae instability strip, and metal rich RR Lyrae
Gustavo E. Medina, Ting S. Li, C. Allende Prieto +39
RR Lyrae stars (RRLs) are valuable probes of both Milky Way assembly and stellar-evolution physics. Using a sample 6,240 RRLs obtained in the first year of the Dark Energy Spectros…
The DESI Y1 RR Lyrae catalog I: Empirical modeling of the cyclic variation of spectroscopic properties and a chemodynamical analysis of the outer halo
Gustavo E. Medina, Ting S. Li, Sergey E. Koposov +44
We present the catalog of RR Lyrae stars (RRLs) observed in the first year of operations of the Dark Energy Spectroscopic Instrument (DESI) survey. This catalog contains 6,240 RRLs…
