DESCRIPTION:Speakers: Florian Niederhofer (Leibniz-Institut für Astrophys
 ik Potsdam (AIP))\nThe Large and Small Magellanic Clouds (LMC and SMC) are
  the largest and most luminous dwarf satellite companions of the Milky Way
 . Due to their close proximity\, they provide a unique opportunity to stud
 y the dynamics of their resolved stellar populations in unparalleled detai
 l. Within the last years\, high-precision proper motion measurements of st
 ars within the Magellanic Clouds had a tremendous impact on our understand
 ing of the Magellanic system and its relation to our own Galaxy. To date\,
  however\, the dynamics of the star cluster systems within the two dwarf g
 alaxies has not received much attention. \nIn this contribution\, I will i
 ntroduce an ongoing observational campaign conducted by our team utilising
  the Hubble Space Telescope (HST) to precisely measure the proper motions 
 of star clusters within the LMC. The exquisite resolution of HST allows us
  to measure precise proper motions of thousands of stars within each clust
 er.\nThe measured motions of the clusters\, combined with photometric and 
 spectroscopic measurements\, will yield their full 6-dimensional phase spa
 ce information within the LMC. I will present first results of the kinemat
 ic structures that are described by clusters of various ages and within di
 fferent structural components of the galaxy. The motions of the clusters c
 an further act as a tracer of the gravitational potential of the LMC and I
  will present preliminary measurements of the mass of the LMC resulting fr
 om the dynamics of the star clusters. Despite its importance in the field 
 of Magellanic Cloud kinematics and evolution\, the mass of the LMC is only
  vaguely known and several studies disagree on it. Our cluster-based study
  will provide an additional independent measurement of the LMC's mass.\n\n
