Possible γ-ray Signals from Low-luminosity Active Galactic Nuclei
2012
Although it has been believed that both emission from an accretion disk and from a jet contributes to the spectral energy distribution of a low-luminosity active galactic nucleus (LLAGN), the respective contribution of them is still an open question. ?-ray signals from LLAGNs can constrain a jet component because a jet component is expected to associate with ?-rays by emission mechanisms similar to powerful blazars and radio galaxies, and then play an important role to understand the physics of disk-jet connection. Here, we demonstrate the ?-ray signals on the assumption that a jet component dominates in X-ray bands, and discuss possible parameter sets on an emission region and the detectability of the ?-rays. In some reasonable cases, Cherenkov Telescope Array can detect ?-rays from a nearby LLAGN.
