Renegade Subhaloes in the Local Group
  Using a dark matter only Constrained Local UniversE Simulation (CLUES) we
examine the existence of subhaloes that change their affiliation from one of
the two prominent hosts in the Local Group (i.e. the Milky Way and the
Andromeda galaxy) to the other, and call these objects "renegade subhaloes". In
light of recent claims that the two Magellanic Clouds (MCs) may have originated
from another region (or even the outskirts) of the Local Group or that they
have been spawned by a major merger in the past of the Andromeda galaxy, we
investigate the nature of such events. However, we cannot confirm that renegade
subhaloes enter as deep into the potential well of their present host nor that
they share the most simplest properties with the MCs, namely mass and relative
velocity. Our simulation rather suggests that these renegade subhaloes appear
to be flying past one host before being pulled into the other. A merger is not
required to trigger such an event, it is rather the distinct environment of our
simulated Local Group facilitating such behavior. Since just a small fraction
of the full z=0 subhalo population are renegades, our study indicates that it
will be intrinsically difficult to distinguish them despite clear differences
in their velocity, radial distribution, shape and spin parameter distributions.
