Abstract
The authors present a sample of 33 extragalactic sources with radio jets and superluminal motions, that includes different types of AGNs: 22 quasars, 6 blazars, 1 Seyfert galaxy, 3 radiogalaxies, and 1 empty field radio source. The observed parameters of the sources and their jets (jet velocity, redshift, fluxes and jet sizes) have been used as input to the relativistic jet model predictions to derive the following model parameters: the source luminosity, the maximum brightness temperature, the characteristic frequency of the synchrotron radiation and the magnetic field. The global parameters of the jets and central sources have been compared, to study the relations between the kinematic and radiative properties of the jets. The results are indicative of a possible relation between the emission mechanisms that are producing the radio properties of the jet sources and their FIR and X-ray emission.
