Internal dynamics of the Large Magellanic Cloud from Gaia DR2
  We use the proper motions (PM) of half a million red giant stars in Large
Magellanic Cloud measured by Gaia to construct a 2d kinematic map of mean PM
and its dispersion across the galaxy, out to 7 Kpc from its centre. We then
explore a range of dynamical models and measure the rotation curve, mean
azimuthal velocity, velocity dispersion profiles, and the orientation of the
galaxy. We find that the circular velocity reaches 90 km/s at 5 Kpc, and that
the velocity dispersion ranges from 30-40 km/s in the galaxy centre to 15-20
km/s at 7 Kpc.
