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…
