Abstract: Periodic quasars are candidates for binary supermassive black holes (BSBHs) efficiently emitting low-frequency gravitational waves. Recently, ∼150 candidates were identified from optical synoptic surveys. However, they may be false positives caused by stochastic quasar variability… read more here.
