Broad-velocity-width Molecular Features in the Galactic Plane
  We performed a systematic search for broad-velocity-width molecular features
(BVFs) in the disk part of our Galaxy by using the CO J = 1-0 survey data
obtained with the Nobeyama Radio Observatory 45 m telescope. From this search,
58 BVFs were identified. In comparisons with the infrared and radio continuum
images, 36 BVFs appeared to have both infrared and radio continuum
counterparts, and 15 of them are described as molecular outflows from young
stellar objects in the literature. In addition, 21 BVFs have infrared
counterparts only, and eight of them are described as molecular outflows in the
literature. One BVF (CO 16.134-0.553) does not have any luminous counterpart in
the other wavelengths, which suggests that it may be an analog of high-velocity
compact clouds in the Galactic center.
