We investigate the hypothesized tidal disruption of the Hercules ultra-faint dwarf galaxy (UFD). Previous tidal disruption studies of the Hercules UFD have been hindered by the hig…
Deep Subaru Hyper Suprime-Cam observations of Milky Way satellites Columba I and Triangulum II
Jeffrey L. Carlin, David J. Sand, Ricardo R. Munoz +9
We present deep, wide-field Subaru Hyper Suprime-Cam photometry of two recently discovered satellites of the Milky Way (MW): Columba I and Triangulum II. The color magnitude diagra…
Structural and Photometric Properties of the Andromeda Satellite Dwarf Galaxy Lacerta I from Deep Imaging with WIYN pODI
Katherine L. Rhode, Denija Crnojevic, David J. Sand +3
We present results from WIYN pODI imaging of Lacerta I (And XXXI), a satellite dwarf galaxy discovered in the outskirts of the Andromeda galaxy (M31) in Pan-STARRS1 survey data. Ou…
