Validation of the DESI 2024 Ly forest BAO analysis using synthetic datasets
Andrei Cuceu, Hiram K. Herrera-Alcantar, Calum Gordon +56
The first year of data from the Dark Energy Spectroscopic Instrument (DESI) contains the largest set of Lyman- (Ly) forest spectra ever observed. This data, collected in the…
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…
