WFPC2 Observations of the Carina Dwarf Spheroidal Galaxy.
The Astronomical Journal, 1997 We present our analysis of Hubble Space Telescope Wide Field Planetary Camera 2 observations in F555W (~V) and F814W (~I) of the Carina dwarf spheroidal galaxy. The resulting V vs (V-I) color-magnitude diagrams reach V ~ 27.1 mag. The reddening of Carina is estimated to be E(V-I) = 0.08 +- 0.02 mag.

Self-interacting Dark Matter Interpretation of Crater II
The Astrophysical Journal LettersThe satellite galaxy Crater II of the Milky Way is extremely cold and exceptionally diffuse. These unusual properties are challenging to understand in the standard model of cold dark matter.

The Origin of High-velocity Stars Considering the Impact of the Large Magellanic Cloud
The Astronomical JournalUtilizing astrometric parameters sourced from Gaia Data Release 3 and radial velocities obtained from various spectroscopic surveys, we identify 519 high-velocity stars (HiVels) with a total velocity in the Galactocentric rest frame greater than 70% of ...

Assessing the Association between the Globular Cluster NGC 4147 and the Sagittarius Dwarf Galaxy
The Astronomical JournalThe potential association of the globular cluster (GC) NGC 4147 with the Sagittarius (Sgr) dwarf spheroidal galaxy has been proposed due to their comparable locations and radial velocities. However, there are still debates about this connection.

Effects of Dark Matter Self-interactions on Sagittarius and its Stream
The Astrophysical JournalThis work explores how assumptions regarding the particle-physics nature of dark matter can alter the evolution of the Sagittarius (Sgr) dwarf spheroidal galaxy and its expansive stellar stream.
