Resumen:
An accretion disk around a supermassive black hole may be strongly perturbed by the
presence of a secondary black hole. Recent simulations have shown that, under certain
conditions, the tidal torques exerted by the secondary black hole may open an annular
gap in the disk. In this regime, matter ?overflows? across the secondary?s orbit to accrete
onto the primary and may feed a pair of relativistic jets.
In this work we study the radiative properties of a binary system of supermassive
black holes, assuming that a relativistic jet is launched from the primary and the migra-
tion of the secondary across the disk proceeds in the ?overflowing? regime. The modified
radiative spectrum of the disk is calculated accounting for strong gravitational effects in
the innermost region. The jet emits non-thermal radiation all along the electromagnetic
spectrum by interaction of locally accelerated electrons with the jet?s magnetic field and
internal and external radiation. In particular, we investigate whether the interaction of
the relativistic electrons with the photons emitted by the accretion disk induces any
signature in the spectral energy distribution of the jet that may reveal the presence of
the secondary black hole.
