We present a spectroscopic survey of 2046 red giant stars, distributed over the central 4 kpc × 2 kpc of the Small Magellanic Cloud (SMC). After fitting and removing a small velocity gradient across the SMC (8.3 km s-1 deg-1 oriented at 234 east of north), we measure an rms velocity scatter of 27.5 ± 0.5 km s-1. The line-of-sight velocity distribution is well-characterized by a Gaussian, and the velocity dispersion profile is nearly constant as a function of radius. We find no kinematic… Expand
A Radial Velocity and Calcium Triplet Abundance Survey of Field Small Magellanic Cloud Giants
We present the results of a pilot wide-field radial velocity and metal abundance survey of red giants in 10 fields in the Small Magellanic Cloud (SMC). The targets lie at projected distances of 0.9Expand
Kinematics of massive stars in the Small Magellanic Cloud
We present radial velocities for 2045 stars in the Small Magellanic Cloud (SMC), obtained from the 2dF survey by Evans et al. The great majority of these stars are of OBA type, tracing the dynamicsExpand
The 3D Kinematics of Gas in the Small Magellanic Cloud
We investigate the kinematics of neutral gas in the Small Magellanic Cloud (SMC) and test the hypothesis that it is rotating in a disk. To trace the 3D motions of the neutral gas distribution, weExpand
A Tidally Stripped Stellar Component of the Magellanic Bridge
Deep photometry of the Small Magellanic Cloud (SMC) stellar periphery (R = 4°, 4.2 kpc) is used to study its line-of-sight depth with red clump (RC) stars. The RC luminosity function is affectedExpand

Kinematical structure of the Magellanic System
Abstract We review our understanding of the kinematics of the LMC and the SMC, and their orbit around the Milky Way. The line-of-sight velocity fields of both the LMC and SMC have been mapped withExpand
Revealing the tidal scars of the Small Magellanic Cloud
Due to their close proximity, the Large and Small Magellanic Clouds (LMC/SMC) provide natural laboratories for understanding how galaxies form and evolve. With the goal of determining the structureExpand
On the dynamics of the Small Magellanic Cloud through high-resolution ASKAP H iobservations
We use new high-resolution H i data from the Australian Square Kilometre Array Pathfinder to investigate the dynamics of the Small Magellanic Cloud (SMC). We model the H i gas component as a rotatingExpand
