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…
Characterization of DESI fiber assignment incompleteness effect on 2-point clustering and mitigation methods for DR1 analysis
D. Bianchi, M. M. S Hanif, A. Carnero Rosell +52
We present an in-depth analysis of the fiber assignment incompleteness in the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1). This incompleteness is caused by the…
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…
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…
Selection of high-redshift Lyman-Break Galaxies from broadband and wide photometric surveys
C. Payerne, W. d'Assignies Doumerg, C. Yèche +44
In this paper, we investigate the possibility of selecting high-redshift Lyman-Break Galaxies (LBG) using current and future broadband wide photometric surveys, such as UNIONS or t…
Stellar reddening map from DESI imaging and spectroscopy
Rongpu Zhou, Julien Guy, Sergey E. Koposov +54
We present new Galactic dust reddening maps of the high Galactic latitude sky using DESI imaging and spectroscopy. We directly measure the reddening of 2.6 million stars by compari…
The clustering of Lyman Alpha Emitting galaxies at z=2-3
M. White, A. Raichoor, Arjun Dey +52
We measure the clustering of Lyman Alpha Emitting galaxies (LAEs) selected from the One-hundred-square-degree DECam Imaging in Narrowbands (ODIN) survey, with spectroscopic follow-…
Archetype-Based Redshift Estimation for the Dark Energy Spectroscopic Instrument Survey
Abhijeet Anand, Julien Guy, Stephen Bailey +46
We present a computationally efficient galaxy archetype-based redshift estimation and spectral classification method for the Dark Energy Survey Instrument (DESI) survey. The DESI s…
The Construction of Large-scale Structure Catalogs for the Dark Energy Spectroscopic Instrument
A. J. Ross, J. Aguilar, S. Ahlen +83
We present the technical details on how large-scale structure (LSS) catalogs are constructed from redshifts measured from spectra observed by the Dark Energy Spectroscopic Instrume…
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…
High redshift LBGs from deep broadband imaging for future spectroscopic surveys
Vanina Ruhlmann-Kleider, Christophe Yèche, Christophe Magneville +60
Lyman break galaxies (LBGs) are promising probes for clustering measurements at high redshift, , a region only covered so far by Lyman- forest measurements. In this paper,…
