We present a study of the evolution of type 1 quasars at , covering the peak epoch of quasar activity. The quasar evolution has been extensively explored by a variety of…
The DESI One-Percent Survey: A concise model for galactic conformity of ELGs
Hongyu Gao, Y. P. Jing, Kun Xu +27
Galactic conformity is the phenomenon in which a galaxy of a certain physical property is correlated with its neighbors of the same property, implying a possible causal relationshi…
A striking relationship between dust extinction and radio detection in DESI QSOs: evidence for a dusty blow-out phase in red QSOs

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…
The DESI One-Percent survey: constructing galaxy-halo connections for ELGs and LRGs using auto and cross correlations
Hongyu Gao, Y. P. Jing, Shanquan Gui +31
In the current Dark Energy Spectroscopic Instrument (DESI) survey, emission line galaxies (ELGs) and luminous red galaxies (LRGs) are essential for mapping the dark matter distribu…
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 …
PROVABGS: The Probabilistic Stellar Mass Function of the BGS One-Percent Survey
ChangHoon Hahn, Jessica Nicole Aguilar, Shadab Alam +33
We present the probabilistic stellar mass function (pSMF) of galaxies in the DESI Bright Galaxy Survey (BGS), observed during the One-Percent Survey. The One-Percent Survey was one…
Detecting and Characterizing Mg II absorption in DESI Survey Validation Quasar Spectra
Lucas Napolitano, Agnesh Pandey, Adam D. Myers +33
We present findings of the detection of Magnesium II (Mg II, λ = 2796, 2803 Å) absorbers from the early data release of the Dark Energy Spectroscopic Instrument (DESI). DESI is pro…
DESI Survey Validation Spectra Reveal an Increasing Fraction of Recently Quenched Galaxies at
David J. Setton, Biprateep Dey, Gourav Khullar +24
We utilize bright Luminous Red Galaxies (LRGs) from the novel Dark Energy Spectroscopic Instrument Survey Validation spectroscopic sample, leveraging its deep ($\sim2.5…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
Hidden depths in the local Universe: The Stellar Stream Legacy Survey
David Martinez-Delgado, Andrew P. Cooper, Javier Roman +26
Mergers and tidal interactions between massive galaxies and their dwarf satellites are a fundamental prediction of the Lambda-Cold Dark Matter cosmology. These events are thought t…
The Sloan Digital Sky Survey Quasar Catalog: Sixteenth Data Release
Brad W. Lyke, Alexandra N. Higley, J. N. McLane +34
We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog compris…
Finding Strong Gravitational Lenses in the DESI DECam Legacy Survey
X. Huang, M. Domingo, A. Pilon +17
We perform a semi-automated search for strong gravitational lensing systems in the 9,000 deg Dark Energy Camera Legacy Survey (DECaLS), part of the DESI Legacy Imaging Surveys…
