No globular cluster progenitors in Milky Way satellite galaxies
  In order to find the possible progenitors of Milky Way globular clusters, we
perform orbit integrations to track the orbits of 151 Galactic globular
clusters and the eleven classical Milky Way satellite galaxies backward in time
for 11 Gyr in a Milky-Way-plus-satellites potential including the effect of
dynamical friction on the satellites. To evaluate possible past associations,
we devise a globular-cluster--satellite binding criterion based on the
satellite's tidal radius and escape velocity and we test it on globular
clusters and satellites associated with the Sagittarius dwarf and with the
Large Magellanic Cloud. For these, we successfully recover the dynamical
associations highlighted by previous studies and we derive their time of
accretion by the Galaxy. Assuming that Milky Way globular clusters are and have
been free of dark matter and thus consist of stars alone, we demonstrate that
none of the globular clusters show any clear association with the eleven
classical Milky Way satellites even though a large fraction of them are
believed to be accreted. This means that accreted globular clusters either came
in as part of now-disrupted satellite galaxies or that globular clusters may
have had dark matter halos in the past -- as suggested by the similar
metallicity between globular clusters and dwarf galaxies.
