A distribution-function estimate of the Milky Way mass profile from outer halo stars in DESI DR2
Gustavo E. Medina, Thomas M. Callingham, Monica Valluri +65
We present measurements of the Milky Way mass using blue horizontal-branch (BHB) and RR Lyrae (RRL) stars from the second data release of DESI (DR2), covering its first three years…
Constraining the Milky Way Mass profile with data driven distribution function using DESI DR2 halo stars
Yanrui Zhou, Jiaxin Han, Wenting Wang +57
We employ a novel data-driven dynamical modeling method, the empirical distribution function (emPDF), to constrain the Milky Way mass profile using a large sample of halo stars fro…
Mock catalogues for the DESI DR2 Milky Way mass modeling effort
Alexander H. Riley, Amanda Byström, Gustavo E. Medina +54
The Dark Energy Spectroscopic Instrument (DESI) survey is an ongoing campaign to obtain millions of spectra, including for stars within the Milky Way. One of DESI's Key Projects fo…
Self Calibrated Galaxy Groups from the DESI DR1 Bright Galaxy Survey
I. Williams, J. Tinker, K. Wang +45
We present a galaxy group catalog built from Data Release 1 of the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey, using the Self Calibrated Group Finder. The alg…
The Binary Fraction of Milky Way Field Stars in DESI: Dependence on Chemical Abundance
Tian Qiu, Wenting Wang, Sergey E. Koposov +39
Binary populations encode information about the physical conditions of star formation and the subsequent evolution of stellar populations. Adopting a statistical method based on mu…
Radio Quasars in the Cosmic Dawn: A Spectroscopic Sample from the DESI Survey
Anniek J. Gloudemans, Jinyi Yang, David M. Alexander +55
We present the largest statistical spectroscopic sample of radio quasars at 4.7<z<6.7 to date. These have been selected from a dedicated Dark Energy Survey Instrument (DESI) target…
DESI Strong Lens Foundry III: Keck Spectroscopy for Strong Lenses Discovered Using Residual Neural Networks
Shrihan Agarwal, Xiaosheng Huang, William Sheu +49
We present spectroscopic data of strong lenses and their source galaxies using the Keck Near-Infrared Echellette Spectrometer (NIRES) and the Dark Energy Spectroscopic Instrument (…
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…
Correcting Turbulence-induced Errors in Fiber Positioning for the Dark Energy Spectroscopic Instrument
E. F. Schlafly, J. Guy, K. Honscheid +37
Highly-multiplexed, robotic, fiber-fed spectroscopic surveys are observing tens of millions of stars and galaxies. For many systems, accurate positioning relies on imaging the fibe…
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…
DESI Bright Galaxy Survey: Final Target Selection, Design, and Validation
ChangHoon Hahn, Michael J. Wilson, Omar Ruiz-Macias +57
Over the next five years, the Dark Energy Spectroscopic Instrument (DESI) will use 10 spectrographs with 5000 fibers on the 4m Mayall Telescope at Kitt Peak National Observatory to…
