The new Milky Way satellites: Alignment with the VPOS and predictions for proper motions and velocity dispersions

Pawlowski, Marcel S; McGaugh, Stacy S.; Jerjen, Helmut


The evidence that stellar systems surrounding the Milky Way (MW) are distributed in a Vast Polar Structure (VPOS) may be observationally biased by satellites detected in surveys of the northern sky. The recent discoveries of more than a dozen new systems in the Southern hemisphere thus constitute a critical test of the VPOS phenomenon. We report that the new objects are located close to the original VPOS, with half of the sample having offsets less than 20 kpc. The positions of the new...[Show more]
