DESCRIPTION:Speakers: Michael Petersen (University of Edinburgh)\nThe ongo
 ing interaction of the Large Magellanic Cloud (LMC) and Milky Way (MW) all
 ows for constraint of the mass (and profile) of both. Through comparison o
 f models of the interaction and 6d halo star data\, we determined that the
  LMC is currently both pulling the MW stellar disc away from the barycentr
 e of the MW at 30 km/s\, as well as inducing a measurable distortion in th
 e outer halos of both the MW and LMC. These effects emphasise the need to 
 move away from equilibrium models when attempting to measure the mass dist
 ributions of either. Models for the M33-M31 interaction -- a similar mass 
 ratio -- reveal a markedly different interaction\, with significantly smal
 ler effects owing to the orbital history.\n\nhttps://iaus379.aip.de/event/
