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 $sim$3 year baseline, using the textit{Hubble Space Telescope} (textit{HST}) Wide Field Camera 3. Combining this data with our previous 5 textit{HST} fields, and an additional 8 measurements from the textit{Gaia}-Tycho Astrometric Solution Catalog, brings us to a total of 43 SMC fields. We measure a systemic motion of $mu_{W}$ = $-0.82$ $pm$ 0.02 (random) $pm$ 0.10 (systematic) mas yr$^{-1}$ and $mu_{N}$ = $-1.21$ $pm$ 0.01 (random) $pm$ 0.03 (systematic) mas yr$^{-1}$. After subtraction of the systemic motion, we find little evidence for rotation, but find an ordered mean motion radially away from the SMC in the outer regions of the galaxy, indicating that the SMC is in the process of tidal disruption. We model the past interactions of the Clouds with each other based on the measured present-day relative velocity between them of $103 pm 26$ km s$^{-1}$. We find that in 97% of our considered cases, the Clouds experienced a direct collision $147 pm 33$ Myr ago, with a mean impact parameter of $7.5 pm 2.5$ kpc.
We present $it{Hubble}$ $it{Space}$ $it{Telescope}$ proper motions in the direction of the star cluster NGC$,$419 in the Small Magellanic Cloud. Because of the high precision of our measurements, for the first time it is possible to resolve the compl
Due to their close proximity, the Large and Small Magellanic Clouds (SMC/LMC) provide natural laboratories for understanding how galaxies form and evolve. With the goal of determining the structure and dynamical state of the SMC, we present new spect
We used data from the near-infrared VISTA survey of the Magellanic Cloud system (VMC) to measure proper motions (PMs) of stars within the Small Magellanic Cloud (SMC). The data analysed in this study comprise 26 VMC tiles, covering a total contiguous
We present a measurement of the systemic proper motion of the Large Magellanic Cloud (LMC) from astrometry with the High Resolution Camera (HRC) of the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope (HST). We observed LMC fields cent
Whether or not the rich star cluster population in the Large Magellanic Cloud (LMC) is affected by significant disruption during the first few x 10^8 yr of its evolution is an open question and the subject of significant current debate. Here, we revi
