Studying baryon acoustic oscillations using photometric redshifts from the DESI Legacy Imaging survey DR9
Christoph Saulder, Yong-Seon Song, Minji Oh +41
Context.The Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Survey DR9 (DR9 hereafter), with its extensive dataset of galaxy locations and photometric redshifts, present…
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…
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 $\…
A dark siren measurement of the Hubble constant with the LIGO/Virgo gravitational wave event GW190412 and DESI galaxies
W. Ballard, A. Palmese, I. Magaña Hernandez +24
We present a measurement of the Hubble Constant using the gravitational wave event GW190412, an asymmetric binary black hole merger detected by LIGO/Virgo, as a dark standard…
