The Proper Motion Field of the Small Magellanic Cloud: Kinematic Evidence for Its Tidal Disruption

We present a new measurement of the systemic proper motion of the Small Magellanic Cloud (SMC), based on an expanded set of 30 fields containing background quasars and spanning a ∼3 year baseline, using the Hubble Space Telescope (HST) Wide Field Camera 3. Combining this data with our previous five...
