Study Identifies Supermassive Black Hole Binaries as Promising Gravitational Wave Targets

A new preprint suggests that specific electromagnetically identified supermassive black hole binaries, such as 3C 66B and Mrk 501, are likely to generate strong gravitational wave signals. This preliminary, non-peer-reviewed research, based on a model fitted to NANOGrav 15-year data, could significantly influence future gravitational wave searches by pinpointing promising individual sources for detection.
