Bodhisattva Sen, Moulinath Banerjee, Michael Woodroofe +2
Whether a dwarf spheroidal galaxy is in equilibrium or being tidally disrupted by the Milky Way is an important question for the study of its dark matter content and distribution.…
Velocity Dispersion Profiles of Seven Dwarf Spheroidal Galaxies
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +4
We present stellar velocity dispersion profiles for seven Milky Way dwarf spheroidal (dSph) satellite galaxies. We have measured 8394 line-of-sight velocities (+/- 2.5 km/s) for 68…
The Michigan/MIKE Fiber System Survey of Stellar Radial Velocities in Dwarf Spheroidal Galaxies: Acquisition and Reduction of Data
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +3
We introduce a stellar velocity survey of dwarf spheroidal galaxies, undertaken using the Michigan/MIKE Fiber System (MMFS) at the Magellan/Clay 6.5 m telescope at Las Campanas Obs…
On Kinematic Substructure in the Sextans Dwarf Spheroidal Galaxy
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +3
We present multifiber echelle radial velocity results for 551 stars in the Sextans dwarf spheroidal galaxy and identify 294 stars as probable Sextans members. The projected velocit…
