HI Observations of two Molecular Clouds with Extremely Large Velocity Dispersions
Harald Riffert, Pawan Kumar, W. K. Huchtmeier
We have mapped two molecular clouds at (l, b) = (3.2 degrees, + 0.3 degrees) and (l, b) = (5.4 degrees, -0.5 degrees) in 21-cm line and continuum emission. These clouds show unusua…
