Remnants of Galactic subhalos and their impact on indirect dark matter
  searches
  Dark matter subhalos, predicted in large numbers in the cold dark matter
scenario, should have an impact on particle dark matter searches. Recent
results show that tidal disruption of these objects in computer simulations is
over-efficient due to numerical artifacts and resolution effects. Accounting
for these results, we re-estimate the subhalo abundance in the Milky Way using
semi-analytical techniques. In particular, we show that the boost factor for
gamma rays and cosmic-ray antiprotons is increased by roughly a factor of two.
