The Binary Fraction of Stars in the Dwarf Galaxy Ursa Minor via Dark Energy Spectroscopic Instrument
Tian Qiu, Wenting Wang, Sergey Koposov +45
We utilize multi-epoch line-of-sight velocity measurements from the Milky Way Survey of the Dark Energy Spectroscopic Instrument to estimate the binary fraction for member stars in…
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…
The Draco Dwarf Spheroidal Galaxy in the First Year of DESI Data
J. Ding, C. Rockosi, Ting S. Li +40
We investigate the spatial distribution, kinematics, and metallicity of stars in the Draco dwarf spheroidal galaxy using data from the Dark Energy Spectroscopic Instrument (DESI).…
Chemodynamics of BoötesI with : Revised Velocity Gradient, Dark Matter Density, and Galactic Chemical Evolution Constraints
Nathan R. Sandford, Ting S. Li, Sergey E. Koposov +14
We combine new spectroscopic observations of the ultra faint dwarf galaxy (UFD) Boötes I (Boo I) from the Southern Stellar Stream Spectroscopic Survey () with 15 years…
The mass of the Milky Way from outer halo stars measured by DESI DR1
Gustavo E. Medina, Ting S. Li, Gwendolyn M. Eadie +50
As a benchmark for galaxy evolution and dark matter studies, the total mass of the Milky Way is a parameter of cosmological significance, and its value at large radii from the Gala…
DESI Data Release 1: Stellar Catalogue
Sergey E. Koposov, Ting S. Li, C. Allende Prieto +65
In this paper we present the stellar Value-Added Catalogue (VAC) based on the DESI Data Release 1. This VAC contains stellar parameter, abundance and radial velocity measurements f…
SN 2023ixf in the Pinwheel Galaxy M101: From Shock Breakout to the Nebular Phase
Weikang Zheng, Luc Dessart, Alexei V. Filippenko +39
We present photometric and spectroscopic observations of SN 2023ixf covering from day one to 442 days after explosion. SN 2023ixf reached a peak -band absolute magnitude of $-18…
