Effects on the local dark matter distribution due to the large magellanic cloud

ABSTRACT We study the local dark matter distribution in two models for Milky Way (MW)-Large Magellanic Cloud (LMC) interaction. The effect of LMC on is dependent evolution MW-LMC system, such that a static model insufficient to accurately velocity solar neighbourhood. An evolved boosts particle velocities by nearly 50 per cent, median value ?750 km s?1. MW particles also experience boost caused disc reflex motion owing infall LMC. implications neighbourhood detection experiments. directionality distinguishable from particles, with difference apparent origin centroid location between and 26 ± 6°. This unique identifier along their high can be utilized directional detectors search originating
