Abstract

We consider the Synchrotron Self-Compton (SSC) model for jets in active galaxies in which produced $\gamma$-ray photons can be absorbed in collisions with the synchrotron radiation already at the emission region. In terms of such modified SSC model, we argue that the higher emission stages should be characterised by $\gamma$-ray spectra extending to lower energies due to the efficient absorption of the highest energy $\gamma$-rays. As an example, we show that different emission stages of the nearby radio galaxy NGC 1275 could be explained by such scenario.
