TL;DR: In this paper, the authors present a measurement of baryonic acoustic oscillations from Lyα absorption and quasars at an effective redshift using the complete extended Baryonic Oscillation Spectroscopic Survey (eBOSS).

TL;DR: In this article, the authors present a measurement of baryonic acoustic oscillations from Lyman-α absorption and quasars at an effective redshift of 2.33$ using the complete extended Baryonic Oscillation Spectroscopic Survey.

TL;DR: The Dark Energy Spectroscopic Instrument (DESI) as mentioned in this paper was designed to explore the nature of dark energy with spectroscopic measurements of 40 million galaxies and quasars and employed the baryon acoustic oscillation method to measure distances from the nearby universe to beyond redshift z > 3.5.

TL;DR: The DESI survey will measure large-scale structure using quasars as direct-tracers of dark matter in the redshift range $0.92 as mentioned in this paper, and two methods are presented to select candidateQUASars for DESI based on imaging in three optical ($g, r, z$) and two infrared ($W1, W2$) bands.

TL;DR: The DESI target selection pipeline is complex and sizable; this paper attempts to summarize the most salient information required to understand and work with DESI targeting data, and examples of how to access and use the desitarget code base as discussed by the authors .
