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…
Field-level inference of growth rate from DESI BGS galaxy and ZTF supernova simulations
Corentin Ravoux, Bastien Carreres, Julian Bautista +60
Galaxy peculiar velocities are a powerful probe of the growth rate of structure at low redshifts (), measured through the combination . These constraints are imp…
Model-Independent Measurement of Baryon Gas Fractions through Galaxy-Galaxy Lensing and the Kinematic Sunyaev-Zel'dovich Effect
R. Henry Liu, Uroš Seljak, Simone Ferraro +52
Baryon feedback is a leading source of systematic uncertainty for cosmology from weak lensing, but measurements of the gas distribution around galaxies have largely relied on param…
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…
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…
ODIN: Spectroscopic Validation of Ly-Emitting Galaxy Samples with DESI
Ethan Pinarski, Govind Ramgopal, Nicole Firestone +65
The One-hundred-deg^2 DECam Imaging in Narrowbands (ODIN) survey is conducting the widest-field deep narrow-band imaging of the equatorial and southern skies. ODIN uses three custo…
The Milky Way stellar halo is twisted and doubly broken: insights from DESI DR2 Milky Way Survey observation
Songting Li, Wenting Wang, Sergey E. Koposov +45
Using K giants from the second data release (DR2) of the Dark Energy Spectroscopic Instrument (DESI) Milky Way (MW) Survey, we measure the shape, orientation, radial profile, and d…
Overview of the DESI Milky Way Survey
Andrew P. Cooper, Sergey E. Koposov, Carlos Allende Prieto +62
We describe the Milky Way Survey (MWS) that will be undertaken with the Dark Energy Spectroscopic Instrument (DESI) on the Mayall 4m telescope at the Kitt Peak National Observatory…
Galaxy bias from galaxy-galaxy lensing in the DES Science Verification Data
J. Prat, C. Sánchez, R. Miquel +68
We present a measurement of galaxy-galaxy lensing around a magnitude-limited () sample of galaxies from the Dark Energy Survey Science Verification (DES-SV) data. We…
Design drivers for a wide-field multi-object spectrograph for the William Herschel Telescope
Marc Balcells, Chris R. Benn, David Carter +21
Wide-field multi-object spectroscopy is a high priority for European astronomy over the next decade. Most 8-10m telescopes have a small field of view, making 4-m class telescopes a…
