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…

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…

DESI DR2 Results III: The Mass of the Milky Way

DESI Collaboration, C. Aganze, J. Aguilar +113

We present measurements of the mass of the Milky Way using distant halo stars selected from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (DR2). We apply four dyna…

The Evolution of the Circumgalactic Medium after a starburst in DESI Post-Starburst Galaxies

Zoe Harvey, Sahyadri Krishna, Rita Tojeiro +45

We present a statistical study of the cool circumgalactic medium (CGM) around massive post-starburst galaxies, traced by Mg II absorption in background quasar s…

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…

Linking neutral gas inflows and outflows to offsets in the star-forming main sequence and mass-metallicity relation

S. Weng, M. Pieri, A. Saintonge +40

Gas inflows and outflows regulate galaxy growth, but direct observational links between measured gas flows and galaxy scaling relations remain limited. Using ~6,000 star-forming ga…

Spatially-Resolved Spectra of Diffuse Galactic Light using 10.8 M DESI Sky Fibers

Andrew K. Saydjari, Bruce T. Draine, Timothy D. Brandt +49

Using 10.8 million ``blank'' sky spectra from the DESI Year 3 dataset, we measure the diffuse galactic light (DGL) spectrum in the optical at spectral resolution by c…

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…

Luminosity function of quasars at from SDSS and DESI

Gaocheng Yin, Linhua Jiang, Zhiwei Pan +54

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…

Cosmic Pairs: A DESI Census of Dual and Offset AGN as Precursors to Massive Black Hole Binaries

Ekaterine Dadiani, Antonella Palmese, Yihao Zhou +52

We present a systematic census of dual and offset active galactic nuclei (AGN) using spectroscopic data from the first data release (DR1) of the Dark Energy Spectroscopic Instrumen…

Beyond traditional emission-line diagnostics: using autoencoders to uncover active galactic nuclei in DESI spectra

J. A. Alcolea, M. Siudek, M. Eriksen +49

The growing volume of spectroscopic data in modern surveys motivates data-driven approaches that complement traditional emission-line diagnostics for active galactic nuclei (AGN) i…

Disentangling the Distant Stellar Halo Using K-Giants in the DESI Year 3 Data

Namitha Kizhuprakkat, Andrew P. Cooper, Wenting Wang +42

We present a sample of 88,959 K-giants from DESI Milky Way Survey Year 3 data, which we use to characterize the chemo-dynamical properties of the stellar halo at Galactocentric dis…
