摘要：
Binary supermassive black holes are expected to be common from galaxy mergers. Their final coalescence is believed to be the loudest gravitational wave siren in the universe, yet no confirmed binary is known to be close enough so that it would efficiently emit gravitational waves to merge within the age of the universe. Over the past few years, systematic searches using synoptic surveys based on active galactic nucleus variability have started to yield a sample of intriguing candidates. I will review the results from these searches and discuss future prospects to confirm systems that are directly emitting low-frequency gravitational waves.
