Description
The unified model of active galactic nuclei includes clouds orbiting closely to the central supermassive black hole with very high velocities. These clouds form the so-called broad-line region, which coexists with the accretion disk. Given the evidence of the infall motion of the clouds, it is expected that they collide with the disk. This scenario might lead to the production of shock waves where particles can be accelerated up to relativistic energies. In our work, we use the Failed Radiatively Accelerated Dusty Outflow (FRADO) model to describe realistically the dynamics of the broad-line region and calculate the expected non-thermal radiation. We found that the impacts of the clouds can produce significant hard X-ray and gamma emission, which could be used to distinguish between BLR models.
