Abstract: According to a hypothesis of the formation process of supermassive black holes in the center of galaxies, a possibility that massive black holes are taken in by galactic merger has been proposed. We aim to discover small- or medium-mass black holes floating in the central region of the galaxy which have not merged yet. We have made VLBI observation to 84 compact radio objects with size smaller than 5 arcsecond selected from the surveys of the Galactic center region by VLA. So far, 16 objects have been detected and the objects have brightness temperature larger than 106 K.
