Vertical flows and structures excited by magnetic activity in the
  Galactic center region
  The vertical flow structure in the galactic center region remains poorly
understood. We analyzed the MHD simulation data by Suzuki et al. (2015) for
better understanding. As a result, we found the fast downflows with a speed of
~100 km/s near the foot-points of magnetic loops. These downflows are flowing
along a magnetic field line and accelerated by the gravity. The direction of
the fast flows is changed by the magnetic loop geometry, as it moves. As a
result, not only vertical motions but also azimuthal and radial motions are
excited. This feature could be relevant to the observed high velocity
dispersion in the position-velocity diagram.
