Modeling of the High Column Density systems in The Lyman-Alpha Forest
T. Tan, J. Rich, E. Chaussidon +41
The Lyman- forests observed in the spectra of high-redshift quasars can be used as a tracer of the cosmological matter density to study baryon acoustic oscillations (BAO) and t…
DESI DR1 Ly 1D power spectrum: The optimal estimator measurement
N. G. Karaçaylı, P. Martini, J. Aguilar +61
The one-dimensional power spectrum of Ly forest offers rich insights into cosmological and astrophysical parameters, including constraints on the sum of neutr…
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…
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 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…
