Spectroscopic Survey of Red Giants in the Small Magellanic Cloud. I. Kinematics
We present a spectroscopic survey of 2046 red giant stars, distributed over the central 4x2 kpc of the Small Magellanic Cloud (SMC). After fitting and removing a small velocity gradient across the SMC (7.9 km/s/deg oriented at 10 deg E of N), we measure an rms velocity scatter of 27.5+-0.5 …
