Systematic uncertainties on DESI Tully-Fisher distances constrained with Integral Field Spectroscopy
Utsav Siwakoti, Lluis Galbany, Kelly A. Douglass +40
The Tully--Fisher (TF) relation is an empirical tool for estimating distances to spiral galaxies. The Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity (PV) Survey uses…
The Extended Baryonic Tully-Fisher Relation for SDSS MaNGA Galaxies
Nitya Ravi, Kelly A. Douglass, Regina Demina
The baryonic Tully-Fisher relation (BTFR), a relationship between rotational velocity and baryonic mass in spiral galaxies, probes the relative content of baryonic and dark matter…
Quantifying the Active Galactic Nuclei Fraction in Cosmic Voids via Mid-Infrared Variability
Anish S. Aradhey, Anca Constantin, Michael S. Vogeley +1
Observations and theoretical simulations suggest that the large scale environment plays a significant role in how galaxies form and evolve and, in particular, whether and when gala…
DeepVoid: A Deep Learning Void Detector
Sam Kumagai, Michael S. Vogeley, Miguel A. Aragon-Calvo +3
We present DeepVoid, an application of deep learning trained on a physical definition of cosmic voids to detect voids in density fields and galaxy distributions. By semantically se…
Data Release 1 of the Dark Energy Spectroscopic Instrument
DESI Collaboration, M. Abdul Karim, A. G. Adame +306
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving three-dimensional s…
DESIVAST: A Catalog of Low-Redshift Voids using Data from the DESI DR1 Bright Galaxy Survey
Hernan Rincon, Segev BenZvi, Kelly Douglass +37
We present three separate void catalogs created using a volume-limited sample of the DESI Year 1 Bright Galaxy Survey. We use the algorithms VoidFinder and V2 to construct void cat…
DESI Peculiar Velocity Survey -- Fundamental Plane
Khaled Said, Cullan Howlett, Tamara Davis +52
The Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity Survey aims to measure the peculiar velocities of early and late type galaxies within the DESI footprint using bot…
The MOST Hosts Survey: spectroscopic observation of the host galaxies of ~40,000 transients using DESI
Maayane T. Soumagnac, Peter Nugent, Robert A. Knop +54
We present the MOST Hosts survey (Multi-Object Spectroscopy of Transient Hosts). The survey is planned to run throughout the five years of operation of the Dark Energy Spectroscopi…
The impact of void-finding algorithms on galaxy classification
Fatima Zaidouni, Dahlia Veyrat, Kelly A. Douglass +1
We explore how the definition of a void influences the conclusions drawn about the impact of the void environment on galactic properties using two void-finding algorithms in the Vo…
A Full Accounting of the Visible Mass in SDSS MaNGA Disk Galaxies
Nitya Ravi, Kelly A. Douglass, Regina Demina
We present a study of the ratio of visible mass to total mass in spiral galaxies to better understand the relative amount of dark matter present in galaxies of different masses and…
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…
A Comparison of Void-Finding Algorithms using Crossing Numbers
Dahlia Veyrat, Kelly A. Douglass, Segev BenZvi
We study how well void-finding algorithms identify cosmic void regions and whether we can quantitatively and qualitatively compare the voids they find with dynamical information fr…
The DESI Survey Validation: Results from Visual Inspection of Bright Galaxies, Luminous Red Galaxies, and Emission Line Galaxies
Ting-Wen Lan, R. Tojeiro, E. Armengaud +79
The Dark Energy Spectroscopic Instrument (DESI) Survey has obtained a set of spectroscopic measurements of galaxies to validate the final survey design and target selections. To as…
