Resumen:
Some active galactic nuclei are supposed to harbor binary systems of
supermassive black holes. They are an attractive target for
gravitational wave experiments. The identification of these systems is
mostly based on the detection of periodic features in their light
curves. Such identifications, however, are far from being conclusive. In
this work we study the perturbations in the emission spectrum of the
accretion disk of the primary black hole caused by the orbital motion of
the secondary. Then we proceed to determine the kind of spectral energy
distributions expected at gamma-ray energies from the inverse Compton
up-scattering of disk photons by relativistic electrons in a jet.
Gamma-ray observations with instruments such as the future Cherenkov
Telescope Array may contribute to a definitive identification of
supermassive binary black hole systems at high-energies.
