Abstract
Gamma‐ray absorption due to photon‐photon pair production of γ‐ray jet photons travelling in the external photon environment of a binary supermassive black hole system is considered. We investigate to what extent the location of a gamma‐ray emitter exposed to the anisotropic radiation field of both accretion disks affects the gamma‐ray opacity. The simple model analysed in this paper consists of a primary black hole surrounded by a standard accretion disk in symbiosis with a relativistic jet. The secondary black hole located at a given position nearby has a similar mass (or smaller) and is surrounded by a viscous Shakura‐Sunyaev small accretion disk. We show that for standard parameters of the accretion disks and a separation distance between the two black holes of 0.05 to 0.1 pc (close system), there is still a significant γ‐ray absorption from the secondary disk.
