CoLoRe-2LPT: Lyman- mock catalogues for the validation of DESI cosmological analyses

M. F. Ruiz-Herrera Bernal, S. Avila, A. Font-Ribera +90

The paper presents fast Lyman‑α forest mock catalogues generated with second‑order Lagrangian perturbation theory (2LPT) that accurately reproduce small‑scale clustering, BAO broad…

DESI DR2 Results IV: Alcock-Paczyński Measurements from the Lyman Alpha Forest and Cosmological Constraints

DESI Collaboration, A. G. Adame, J. Aguilar +164

The DESI DR2 analysis measures the Alcock‑Paczynski effect using the full shape of Lyman‑α forest auto‑ and cross‑correlations, achieving 1% precision at redshift 2.33 and providin…

Probing the limits of cosmological information from the Lyman- forest 2-point correlation functions

Wynne Turner, Andrei Cuceu, Paul Martini +48

The standard cosmological analysis with the Ly forest relies on a continuum fitting procedure that suppresses information on large scales and distorts the three-dimensional cor…

Calibrating redshift distributions at with Lyman- forest cross-correlations

Qianjun Hang, Laura Casas, William d'Assignies +3

We explore the feasibility of using Lyman- (Ly) forests to calibrate the ensemble redshift distribution of the high-redshift tail () of photometric galaxies. We use…

Data Release 1 of the Dark Energy Spectroscopic Instrument

DESI Collaboration, M. Abdul Karim, A. G. Adame +306

In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving three-dimensional s…

The Lyman- Forest from LBGs: First 3D Correlation Measurement with DESI and Prospects for Cosmology

Hiram K. Herrera-Alcantar, Eric Armengaud, Christophe Yèche +50

The Lyman- (Ly) forest is a key tracer of large-scale structure at redshifts z > 2, traditionally studied using spectra of quasars. Here, we explore the viability Lyman Bre…
