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…
Constraining the Galactic bar using the M92 stellar stream
Amanda Byström, Sergey E. Koposov, Ting. S. Li +42
Stellar streams are excellent probes of the gravitational potential in which they evolve. In the Milky Way (MW), globular cluster (GC) streams are routinely used to infer propertie…
Characterizing the GD-1 Stream with DESI DR2 Data: Thin Stream and Hot Cocoon
Emma Jarvis, Ting S. Li, Sergey E. Koposov +54
GD-1 is among the longest, coldest stellar streams in the Milky Way, making it an ideal target for probing dark matter substructure through dynamical heating. We present a catalog…
The velocity field of our Milky Way outer stellar halo based on DESI DR2
Songting Li, Wenting Wang, Sergey E. Koposov +53
Using 64,000 halo K giants from Dark Energy Spectroscopic Instrument (DESI) second Data Release (DR2), we decompose the Milky Way (MW) stellar halo between 3 and 160 kpc into metal…
The Kinematically Hot, Extremely Metal-Poor C-19 Stellar Stream in DESI DR2
Nasser Mohammed, Joseph Y. Tang, Ting S. Li +47
Stellar streams are the result of a host galaxy's gravitational potential tidally disrupting satellite dwarf galaxies and globular clusters (GCs), causing them to grow leading and…
Signatures of a Tidally Induced Spiral Arm at the Anticenter of the Milky Way and a Kinematically Extended Anticenter Stream Using DESI DR2
Mika Lambert, Constance M. Rockosi, Sergey E. Koposov +46
Using the Dark Energy Spectroscopic Instrument Milky Way Survey (DESI MWS), we examine the 6D space of the anticenter region of the stellar disk (150 Galactic longitude…
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).…
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…
The Backup Program of the Dark Energy Spectroscopic Instrument's Milky Way Survey
Arjun Dey, Sergey E. Koposov, Joan R. Najita +66
The Milky Way Backup Program (MWBP), a survey currently underway with the Dark Energy Spectroscopic Instrument (DESI) on the Nicholas U. Mayall 4-m Telescope, works at the margins…
The DESI Y1 RR Lyrae catalog II: The metallicity dependency of pulsational properties, the shape of the RR Lyrae instability strip, and metal rich RR Lyrae
Gustavo E. Medina, Ting S. Li, C. Allende Prieto +39
RR Lyrae stars (RRLs) are valuable probes of both Milky Way assembly and stellar-evolution physics. Using a sample 6,240 RRLs obtained in the first year of the Dark Energy Spectros…
The Cocytos Stream: A Disrupted Globular Cluster from our Last Major Merger?
Christian Aganze, Vedant Chandra, Risa H. Wechsler +48
The census of stellar streams and dwarf galaxies in the Milky Way provides direct constraints on galaxy formation models and the nature of dark matter. The DESI Milky Way survey --…
