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…
Measurement of the small-scale 3D Lyman- forest power spectrum
Marie Lynn Abdul-Karim, Eric Armengaud, Guillaume Mention +3
Small-scale correlations measured in the Lyman- (Ly) forest encode information about the intergalactic medium and the primordial matter power spectrum. In this article, we pr…
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…
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…
Optimal 1D Ly Forest Power Spectrum Estimation -- III. DESI early data
Naim Göksel Karaçaylı, Paul Martini, Julien Guy +59
The one-dimensional power spectrum of the Ly forest provides important information about cosmological and astrophysical parameters, including constraints on wa…
The Lyman- forest catalog from the Dark Energy Spectroscopic Instrument Early Data Release
César Ramírez-Pérez, Ignasi Pérez-Ràfols, Andreu Font-Ribera +67
We present and validate the catalog of Lyman- forest fluctuations for 3D analyses using the Early Data Release (EDR) from the Dark Energy Spectroscopic Instrument (DESI) survey.…
The Dark Energy Spectroscopic Instrument: One-dimensional power spectrum from first Lyman- forest samples with Fast Fourier Transform
Corentin Ravoux, Marie Lynn Abdul-Karim, Eric Armengaud +63
We present the one-dimensional Lyman- forest power spectrum measurement using the first data provided by the Dark Energy Spectroscopic Instrument (DESI). The data sample compris…
The Early Data Release of the Dark Energy Spectroscopic Instrument
DESI Collaboration, A. G. Adame, J. Aguilar +266
The Dark Energy Spectroscopic Instrument (DESI) completed its five-month Survey Validation in May 2021. Spectra of stellar and extragalactic targets from Survey Validation constitu…
Validation of the Scientific Program for the Dark Energy Spectroscopic Instrument
DESI Collaboration, A. G. Adame, J. Aguilar +261
The Dark Energy Spectroscopic Instrument (DESI) was designed to conduct a survey covering 14,000 deg over five years to constrain the cosmic expansion history through precise m…
Performance of the Quasar Spectral Templates for the Dark Energy Spectroscopic Instrument
Allyson Brodzeller, Kyle Dawson, Stephen Bailey +44
Millions of quasar spectra will be collected by the Dark Energy Spectroscopic Instrument (DESI), leading to a four-fold increase in the number of known quasars. High accuracy quasa…
A framework to measure the properties of intergalactic metal systems with two-point flux statistics
Naim Göksel Karaçaylı, Paul Martini, David H. Weinberg +16
The abundance, temperature, and clustering of metals in the intergalactic medium are important parameters for understanding their cosmic evolution and quantifying their impact on c…
