DESI 2024 VII: Cosmological Constraints from the Full-Shape Modeling of Clustering Measurements
DESI Collaboration, A. G. Adame, J. Aguilar +210
We present cosmological results from the measurement of clustering of galaxy, quasar and Lyman- forest tracers from the first year of observations with the Dark Energy Spectrosc…
DESI 2024 II: Sample Definitions, Characteristics, and Two-point Clustering Statistics
DESI Collaboration, A. G. Adame, J. Aguilar +200
We present the samples of galaxies and quasars used for DESI 2024 cosmological analyses, drawn from the DESI Data Release 1 (DR1). We describe the construction of large-scale struc…
DESI 2024 V: Full-Shape Galaxy Clustering from Galaxies and Quasars
A. G. Adame, J. Aguilar, S. Ahlen +195
We present the measurements and cosmological implications of the galaxy two-point clustering using over 4.7 million unique galaxy and quasar redshifts in the range divi…
The atomic gas sequence and mass-metallicity relation from dwarfs to massive galaxies
D. Scholte, A. Saintonge, J. Moustakas +43
Galaxy scaling relations provide insights into the processes that drive galaxy evolution. The extension of these scaling relations into the dwarf galaxy regime is of particular int…
DESI Early Data Release Milky Way Survey Value-Added Catalogue
Sergey E. Koposov, C. Allende-Prieto, A. P. Cooper +40
We present the stellar value-added catalogue based on the Dark Energy Spectroscopic Instrument (DESI) Early Data Release. The catalogue contains radial velocity and stellar paramet…
Constraints on the spacetime variation of the fine-structure constant using DESI emission-line galaxies
Linhua Jiang, Zhiwei Pan, Jessica Nicole Aguilar +38
We present strong constraints on the spacetime variation of the fine-structure constant using the Dark Energy Spectroscopic Instrument (DESI). In this pilot work, we utilize $\…
DESI 2024 III: Baryon Acoustic Oscillations from Galaxies and Quasars
DESI Collaboration, A. G. Adame, J. Aguilar +193
We present the DESI 2024 galaxy and quasar baryon acoustic oscillations (BAO) measurements using over 5.7 million unique galaxy and quasar redshifts in the range 0.1<z<2.1. Divided…
DESI 2024 VI: Cosmological Constraints from the Measurements of Baryon Acoustic Oscillations
DESI Collaboration, A. G. Adame, J. Aguilar +200
We present cosmological results from the measurement of baryon acoustic oscillations (BAO) in galaxy, quasar and Lyman- forest tracers from the first year of observations from t…
DESI 2024 IV: Baryon Acoustic Oscillations from the Lyman Alpha Forest
DESI Collaboration, A. G. Adame, J. Aguilar +196
We present the measurement of Baryon Acoustic Oscillations (BAO) from the Lyman- (Ly) forest of high-redshift quasars with the first-year dataset of the Dark Energy Spectrosc…
Constraining primordial non-Gaussianity from the large scale structure two-point and three-point correlation functions
Z. Brown, R. Demina, A. G. Adame +47
Surveys of cosmological large-scale structure (LSS) are sensitive to the presence of local primordial non-Gaussianity (PNG), and may be used to constrain models of inflation. Local…
The frequency of metal-enrichment of cool helium-atmosphere white dwarfs using the DESI Early Data Release
Christopher J. Manser, Boris T. Gänsicke, Paula Izquierdo +35
There is overwhelming evidence that white dwarfs host planetary systems; revealed by the presence, disruption, and accretion of planetary bodies. A lower limit on the frequency of…
The DESI Early Data Release White Dwarf Catalogue
Christopher J. Manser, Paula Izquierdo, Boris T. Gänsicke +51
The Early Data Release (EDR) of the Dark Energy Spectroscopic Instrument (DESI) comprises spectroscopy obtained from 2020 December 14 to 2021 June 10. White dwarfs were targeted by…
