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…
Investigating the galaxy-halo connection of DESI Emission-Line Galaxies with SHAMe-SF
Sara Ortega-Martinez, Sergio Contreras, Raul E. Angulo +1
The Dark Energy Spectroscopic Instrument (DESI) survey is mapping the large-scale distribution of millions of Emission Line Galaxies (ELGs) over vast cosmic volumes to measure the…
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…
ForestFlow: predicting the Lyman- forest clustering from linear to nonlinear scales
J. Chaves-Montero, L. Cabayol-Garcia, M. Lokken +31
On large scales, the Lyman- forest provides insights into the expansion history of the Universe, while on small scales, it imposes strict constraints on the growth history, the…
Validating the clustering predictions of empirical models with the FLAMINGO simulations
Sergio Contreras, Raul E. Angulo, Jonás Chaves-Montero +3
Context. Mock galaxy catalogues are essential for correctly interpreting current and future generations of galaxy surveys. Despite their significance in galaxy formation and cosmol…
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…
Synthetic spectra for Lyman- forest analysis in the Dark Energy Spectroscopic Instrument
Hiram K. Herrera-Alcantar, Andrea Muñoz-Gutiérrez, Ting Tan +51
Synthetic data sets are used in cosmology to test analysis procedures, to verify that systematic errors are well understood and to demonstrate that measurements are unbiased. In th…
