At this point, the binary starts emitting gravitational radiation efficiently, loses energy and angular momentum, and finally merges. The gravitational waves emitted by these systems are the target of current Pulsar Timing Arrays and of future interferometers as LISA (Laser Interferometer Space Antenna). Unlike most stellar-mass black hole mergers, supermassive black hole binaries (SMBHBs) live and die in gas rich environments (the cores of galaxies) and they can present similar phenomenology to single AGNs; namely, accretion disks, jets and the subsequent multiwavelength emission. In this talk, I will present some late results on theoretical predictions of the electromagnetic emission from accretion disks and jets in SMBHBs approaching merger. A detailed knowledge of the main radiation signatures from these systems is crucial to differentiate them from normal AGNs and to identify potential targets for the future gravitational wave observatories.</span></div>
