Query: Super Massive Black Holes and the Origin of High-Velocity Stars   The origin of high velocity stars observed in the halo of our Galaxy is still
unclear. In this work we test the hypothesis, raised by results of recent high
precision $N$-body simulations, of strong acceleration of stars belonging to a
massive globular cluster orbitally decayed in the central region of the host
galaxy where it suffers of a close interaction with a super massive black hole,
which, for these test cases, we assumed $10^8$ M$_\odot$ in mass.
