Clouds in arms.

BELOKUROV V.A. and ERKAL D.

Abstract (from CDS):

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.
