Collimated Winds from Active Galactic Nuclei
We present a wind-type model for the modulation of jet brightness (knots) on kpc scale. It is shown that the mass distribution of the parent galaxy and the development of unstable modes on the surface of the beam can lead to the periodic formation of internal shocks that can be associated with enhanced particle acceleration. The results are compared specifically with the data of the jet of M87.
