"A precessing nozzle in the jet of BL Lac?" |
Abstract:
The precession of the jet in S433 is a result of the influence of the binary partner to the star from which it emerges. I will describe recent observations suggesting that similar precession may occur in some extragalactic jets. It has been suggested that this may be due to a presence of a binary system consisting of two extremely massive black holes. |
