Broad-velocity-width Molecular Features in the Galactic Plane

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