Abstract: Supermassive black holes (SMBHs) are ubiquitous in the centers of massive galaxies. Observations reveal that SMBHs are intimately linked to the properties of their host galaxies, as evidenced by scaling relationships. SMBH mergers, which occur as a natural consequence of galaxy mergers, play a critical role in shaping both the SMBHs themselves and the galaxies that host them. The formation and evolution history of SMBHs, such as the mechanism that drives SMBH binaries to merge and the role SMBH mergers play in mass assemble are barely known due to the limit of observations. The detection of gravitational waves from SMBH binaries provide a prob to these problems. I will introduce our recent works on probing the merger rate and delay time of SMBH binaries through future space-based gravitational wave detectors (such as LISA) and pulsar timing arrays, and discuss what we can learn from gravitational wave detections.
