Query: Star Clusters and Super Massive Black Holes: High Velocity Stars
  Production   One possible origin of high velocity stars in the Galaxy is that they are the
product of the interaction of binary systems and supermassive black holes. We
investigate a new production channel of high velocity stars as due to the close
interaction between a star cluster and supermassive black holes in galactic
centres. The high velocity acquired by some stars of the cluster comes from
combined effect of extraction of their gravitational binding energy and from
the slingshot due to the interaction with the black holes. Stars could reach a
velocity sufficient to travel in the halo and even overcome the galactic
potential well, while some of them are just stripped from the cluster and start
orbiting around the galactic centre.
