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…
