Optimizing Optical Searches for Supermassive Black Hole Binaries in AGN Light Curves: Fourier versus Bayesian Periodicity Detection
Sebastian Banaszak, Caitlin Witt, Adam Miller
Simulations predict that supermassive black hole binaries (SMBHBs) will exhibit periodic brightness variations that may exceed the stochastic variability intrinsic to active galact…

Multi-messenger Analysis of Supermassive Black Hole Binaries: The Joint-likelihood Approach
Maria Charisi, Stephen Taylor, Jessie Runnoe +2
Supermassive black hole binaries (SMBHBs) formed in galaxy mergers are promising multi-messenger sources. They can be identified as quasars with periodic variability in electromagn…
