| Outline of Final Research Achievements |
This project aims to search intermediate-mass black holes (IMBHs) and unidentified super star clusters (SSCs) which may be embedded in the central molecular zone of our Galaxy. Intensive observations of "high-velocity compact clouds", which have been found by our group, with large millimeter and submillimeter-wave telescopes were performed. During the three years project period, we succeeded to found a promissing candidate of IMBH and two SSC candidates. In addition, we detected several candidates for invisible, isolated black holes in the CMZ as well as in the Galactic disk. These might be essential ingredients of galaxies which may contribute to the formation and evolution of supermassive black holes in galactic nuclei.
