Structure of the nucleus of 1928+738
J. Roland, S. Britzen, E. Kun +3
Modeling of the trajectories of VLBI components ejected by the nucleus of 1928+738 shows the VLBI jet contains three families of trajectories, i.e. VLBI components are ejected from…
Kinematic study of the parsec-scale jet of the quasar PKS 1741--03
Anderson Caproni, Iara Tosta e Melo, Zulema Abraham +2
We present 23 interferometric images of parsec-scale jet of the quasar PKS 1741--03 at 15, 24 and 43 GHz spanning about 13 yr. We model the images as a superposition of discrete tw…
Radio quasars and the link with GAIA
J. Roland
Modeling VLBI ejections of nuclei of extragalactic radio sources, indicates that their nuclei contain a binary black hole system. One can derive the distance and the positions of t…
Binary black holes in nuclei of extragalactic radio sources
J. Roland, S. Britzen, A. Caproni +3
If we assume that nuclei of extragalactic radio sources contain binary black hole systems, the two black holes can eject VLBI components in which case two families of different VLB…
A supermassive binary black hole in the quasar 3C345
A. P. Lobanov, J. Roland
Radio loud active galactic nuclei present a remarkable variety of signs indicating the presence of periodical processes possibly originating in binary systems of supermassive black…
