DESI DR1 Ly 1D power spectrum: Validation of estimators
N. G. Karaçaylı, C. Ravoux, P. Martini +53
The Data Release 1 (DR1) of the Dark Energy Spectroscopic Instrument (DESI) is the largest sample to date for small-scale Ly forest cosmology, accessed through its one-dimensio…
DESI DR1 Lyα 1D power spectrum: The Fast Fourier Transform estimator measurement
Corentin Ravoux, Marie-Lynn Abdul-Karim, Jean-Marc Le Goff +64
We present the one-dimensional Lyman- forest power spectrum measurement derived from the data release 1 (DR1) of the Dark Energy Spectroscopic Instrument (DESI). The measuremen…
Constraints on Neutrino Physics from DESI DR2 BAO and DR1 Full Shape
W. Elbers, A. Aviles, H. E. Noriega +116
The Dark Energy Spectroscopic Instrument (DESI) Collaboration has obtained robust measurements of baryon acoustic oscillations (BAO) in the redshift range, , based o…
Construction of the Damped Ly Absorber Catalog for DESI DR2 Ly BAO
A. Brodzeller, M. Wolfson, D. M. Santos +96
We present the Damped Ly Toolkit for automated detection and characterization of Damped Ly absorbers (DLA) in quasar spectra. Our method uses quasar spectral templates with…
Extended Dark Energy analysis using DESI DR2 BAO measurements
K. Lodha, R. Calderon, W. L. Matthewson +122
We conduct an extended analysis of dark energy constraints, in support of the findings of the DESI DR2 cosmology key paper, including DESI data, Planck CMB observations, and three…
Validation of the DESI DR2 Measurements of Baryon Acoustic Oscillations from Galaxies and Quasars
U. Andrade, E. Paillas, J. Mena-Fernández +116
The Dark Energy Spectroscopic Instrument (DESI) data release 2 (DR2) galaxy and quasar clustering data represents a significant expansion of data from DR1, providing improved stati…
