abstract
Supermassive black hole binaries (SMBHBs) are expected by the hierarchical galaxy formation model in ΛCDM cosmology. A binary may become stalling at the parsec scale and is expected to be detected in nearby normal gas-poor galaxies, which are have not yet comfirmed by observations because we do not have efficient methods to detect them. In this talk, I will introduce a possible method to detect a SMBHB in normal galaxies. As in the hierarchical galaxy formation model, today's galaxies are the product of frequent galaxy merging, triggering the activity of active galactic nuclei in gas-rich mergers. During the talk, we will also investigate the interaction of SMBBHs and an accretion disc and show that the stalling can be avoided due to reached, which would give rise to the rich observational signatures.
