The Lyman- (Ly) forest has become a crucial probe for studying the large-scale structure of the universe at high redshift (), providing powerful constraints on Baryon…
Lyman- forest holography: 3D predictions from 1D measurements
J. Chaves-Montero, A. Font-Ribera, J. Aguilar +68
Cosmological analyses of Lyman- forest clustering rely on either one-dimensional correlations along individual sightlines or three-dimensional correlations between different sig…
Fiducial-Cosmology-dependent systematics for the DESI 2024 Full-Shape Analysis
R. Gsponer, S. Ramirez-Solano, F. Rodríguez-Martínez +65
We assess the impact of the fiducial cosmology choice on cosmological inference from full-shape (FS) fits of the galaxy power spectrum in the DESI 2024 Data Release 1 (DR1). Using…
