Mock data sets for the Eboss and DESI Lyman- forest surveys
Thomas Etourneau, Jean-Marc Le Goff, James Rich +32
We present a publicly-available code to generate sets of mock Lyman- (\lya) forest data that have realistic large-scale correlations including those due to the Baryonic Acoustic…
Optimal data compression for Lyman- forest cosmology
Francesca Gerardi, Andrei Cuceu, Benjamin Joachimi +2
The Lyman- (Ly) three-dimensional correlation functions have been widely used to perform cosmological inference using the baryon acoustic oscillation (BAO) scale. While the t…
DESI luminous red galaxy samples for cross-correlations
Rongpu Zhou, Simone Ferraro, Martin White +36
We present two galaxy samples, selected from DESI Legacy Imaging Surveys (LS) DR9, with approximately 20,000 square degrees of coverage and spectroscopic redshift distributions des…
Broad Absorption Line Quasars in the Dark Energy Spectroscopic Instrument Early Data Release
S. Filbert, P. Martini, K. Seebaluck +41
Broad absorption line (BAL) quasars are characterized by gas clouds that absorb flux at the wavelength of common quasar spectral features, although blueshifted by velocities that c…
A striking relationship between dust extinction and radio detection in DESI QSOs: evidence for a dusty blow-out phase in red QSOs
V. A. Fawcett, D. M. Alexander, A. Brodzeller +39
We present the first eight months of data from our secondary target program within the ongoing Dark Energy Spectroscopic Instrument (DESI) survey. Our program uses a mid-infrared a…
3D Correlations in the Lyman- Forest from Early DESI Data
Calum Gordon, Andrei Cuceu, Jonás Chaves-Montero +56
We present the first measurements of Lyman- (Ly) forest correlations using early data from the Dark Energy Spectroscopic Instrument (DESI). We measure the auto-correlation of…
