Dynamics of Milky Way globular clusters and satellites
in the Gaia era

I discuss the current state of the art in dynamical studies of Milky Way globular clusters and satellite galaxies, particularly since the second Gaia data release in 2018. The high precision of Gaia astrometry makes it possible to explore the internal dynamics of many of these objects, measuring their mass distribution and uncovering their past evolution. At the same time, the kinematics of the entire system of star clusters and satellites can be used to probe the Milky Way potential, although the interpretation is complicated by the ongoing interaction between our Galaxy and the Large Magellanic Cloud.
Eugene Vasiliev is a postdoctoral researcher at the Institute of Astronomy, Cambridge, UK, working in the field of galactic dynamics across a range of scales - from galactic nuclei with supermassive black holes to the entire Milky Way and its satellites.
