We present three-dimensional (3D) kinematics of Sagittarius (Sgr) trailing tidal debris in six fields located 70°-130° along the stream from the Sgr dwarf galaxy core. The data are from our proper-motion (PM) survey of Kapteyn's Selected Areas, in which we have measured accurate PMs to faint magnitudes in ~40' × 40' fields evenly spaced across the sky. The radial velocity (RV) signature of Sgr has been identified among our follow-up spectroscopic data in four of the six fields and combined with… Expand
Metallicity and α-Element Abundance Gradients along the Sagittarius Stream as Seen by APOGEE
