Clouds in Arms
  We use astrometry and broad-band photometry from Data Release 2 of the ESA's
Gaia mission to map out low surface-brightness features in the stellar density
distribution around the Large and Small Magellanic Clouds. The LMC appears to
have grown two thin and long stellar streams in its Northern and Southern
regions, highly reminiscent of spiral arms. We use computer simulations of the
Magellanic Clouds' in-fall to demonstrate that these arms were likely pulled
out of the LMC's disc due to the combined influence of the SMC's most recent
fly-by and the tidal field of the Milky Way.
