Scientific paper

Supermassive black holes presumably grow through numerous mergers throughout cosmic time. During each merger, supermassive black hole binaries are surrounded by a circumbinary accretion disk that imposes a significant magnetic field. The motion of the binary through that field will convert the field energy to Poynting flux and thence to synchrotron emission at radio frequencies. We find that the short timescales of many mergers will limit their detectability with most planned blind surveys, independent of the details of the emission process and flux distribution. Radio surveys may be able to detect the weaker emission produced by the binary's motion as it is modulated by spin-orbit precession and inspiral well in advance of merger.
