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…
Siena Galaxy Atlas 2020
John Moustakas, Dustin Lang, Arjun Dey +8
We present the 2020 version of the Siena Galaxy Atlas (SGA-2020), a multi-wavelength optical and infrared imaging atlas of 383,620 nearby galaxies. The SGA-2020 uses optical …
The CluMPR Galaxy Cluster-Finding Algorithm and DESI Legacy Survey Galaxy Cluster Catalogue
M. J. Yantovski-Barth, Jeffrey A. Newman, Biprateep Dey +4
Galaxy clusters enable unique opportunities to study cosmology, dark matter, galaxy evolution, and strongly-lensed transients. We here present a new cluster-finding algorithm, CluM…
Astrometric Calibration and Performance of the Dark Energy Spectroscopic Instrument Focal Plane
S. Kent, E. Neilsen, K. Honscheid +46
The Dark Energy Spectroscopic Instrument, consisting of 5020 robotic fiber positioners and associated systems on the Mayall telescope at Kitt Peak, Arizona, is carrying out a surve…
The DESI One-Percent Survey: Exploring A Generalized SHAM for Multiple Tracers with the UNIT Simulation
Jiaxi Yu, Cheng Zhao, Violeta Gonzalez-Perez +40
We perform SubHalo Abundance Matching (SHAM) studies on UNIT simulations with \{\}-SHAM and \{\}-SHAM. They are designe…
Survey Operations for the Dark Energy Spectroscopic Instrument
E. F. Schlafly, D. Kirkby, D. J. Schlegel +47
The Dark Energy Spectroscopic Instrument (DESI) survey is a spectroscopic survey of tens of millions of galaxies at covering 14,000 square degrees of the sky. In its…
Comparing the Photometric Calibration of DESI Imaging and Gaia Synthetic Photometry
Rongpu Zhou, Arjun Dey, Dustin Lang +3
The relative photometric calibration errors in the DESI Legacy Imaging Surveys (LS), which are used for DESI target selection, can leave imprints on the DESI target densities and b…
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…
Constraining primordial non-Gaussianity from DESI quasar targets and Planck CMB lensing
Alex Krolewski, Will J. Percival, Simone Ferraro +33
We detect the cross-correlation between 2.7 million DESI quasar targets across 14,700 deg (180 quasars deg) and Planck 2018 CMB lensing at 30. We use the cross-…
First Detection of the BAO Signal from Early DESI Data
Jeongin Moon, David Valcin, Michael Rashkovetskyi +65
We present the first detection of the baryon acoustic oscillations (BAO) signal obtained using unblinded data collected during the initial two months of operations of the Stage-IV…
Target Selection for the DESI Peculiar Velocity Survey
Christoph Saulder, Cullan Howlett, Kelly A. Douglass +35
We describe the target selection and characteristics of the DESI Peculiar Velocity Survey, the largest survey of peculiar velocities (PVs) using both the fundamental plane (FP) and…
DESI z >~ 5 Quasar Survey. I. A First Sample of 400 New Quasars at z ~ 4.7-6.6
Jinyi Yang, Xiaohui Fan, Ansh Gupta +39
We report the first results of a high-redshift ( >~ 5) quasar survey using the Dark Energy Spectroscopic Instrument (DESI). As a DESI secondary target program, this survey is de…
