Abstract: We have developed a model for the variability of gamma-ray emission in jets of active galactic nuclei (AGN) in which the variability arises as a result of photon-photon pair production interactions with X-rays emitted by a hotspot in the inner part of the accretion disc. As the hotspot orbits around the central engine, the amount of absorption varies. Our model may account for the observed variability of TeV emission from Markarian 421, as well as correlated variations of the X-ray and TeV gamma-ray flux. © 1997 RAS.
