| Research Abstract |
By our high-precision monitoring observations at millimeter wavelengths, we successfully detected the periodic variation a periodic flux variation from the center of a giant galaxy. This and our past observations provided possible evidence that binary black holes exist in the center of giant galaxies. The black hole merger is one of the most spectacular natural phenomena in the universe and our observational results show that the black hole collisions may have important implications for the formation of a supermassive black hole in the evolution process.
