Velocity bridges: signature of HVC interaction with the Galactic halo.

PIETZ J., KERP J., KALBERLA P.M.W., MEBOLD U., BURTON W.B. and HARTMANN D.H.

Abstract (from CDS):

We present observational evidence for the existence of "velocity bridges" between high-velocity clouds (HVCs) and neutral gas at lower velocities towards HVC complex C. The velocity bridges (VBs henceforward) show up as faint 21-cm line emission filaments (TB∼0.2K) connecting the two velocity regimes over velocity gaps of 20 to 100km/s. We interpret VBs as indicators of energetic interactions of HVCs with gas in the galactic halo or the disk-halo interface.
