Abstract: High-velocity compact clouds (HVCCs) are peculiar molecular clouds detected in the central molecular zone (CMZ) of our Galaxy. Some of the HVCCs are considered to have been formed by the encounters with compact massive objects. To examine the uniqueness of HVCCs to the CMZ, we performed a systematic search for broad-velocity-width molecular features (BVFs) in the disk part of our Galaxy. We identified 60 BVFs in the CO Galactic plane survey data, and most of them are associated with young stellar objects. One BVF, CO 16.13–0.55, does not have any luminous counterparts in the other wavelengths, providing a promising candidate for HVCCs in the Galactic disk.
