Joint Modeling of GD-1 and C-19 as Old Streams
Raymond G. Carlberg, Ting S. Li, Emma Jarvis +39
DESI observational data for the GD-1 and C-19 streams are compared to stream simulations in an evolving multi-halo potential of a Milky Way-like galaxy based on a cosmological Milk…
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 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…
Faraday tomography with CHIME: the `tadpole' feature G137+7
Nasser Mohammed, Anna Ordog, Rebecca A. Booth +27
A direct consequence of Faraday rotation is that the polarized radio sky does not resemble the total intensity sky at long wavelengths. We analyze G137+7, which is undetectable in…
