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…
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…
