Title of the communication: Jets and accretion processes in Active
Galactic Nuclei: further clues
Preliminary abstract (12 lines max.):
We present evidence in favour of a strong link between
the luminosity radiatively dissipated in the central engine of radio--loud
Active Galactic Nuclei and the kinetic power in their jets. This piece of
evidence is based on the relation we find between the luminosity in broad
emission lines and the kinetic power in pc--scale radio jets, for a sample
of radio--loud quasars for which suitable data are available in the
literature. A strong magnetic field in equipartition with the radiation
field could be responsible for regulating both processes. BL Lac objects
seem to follow a similar behaviour, but with a comparatively fainter broad
line emission.
