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…
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…
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…
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…
DESIVAST: A Catalog of Low-Redshift Voids using Data from the DESI DR1 Bright Galaxy Survey
Hernan Rincon, Segev BenZvi, Kelly Douglass +40
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…
