The kinetic luminosity of radio jets in active galactic nuclei

摘要：

Based on the Konigls inhomogeneous jet model, we estimate the jet parameters, such as bulk Lorentz factor Γ. viewing angle θ and electron number density n<,e> from radio VLBI and X-ray data for a sample of active galactic nuclei (AGNs). The kinetic luminosity of jets is then calculated using the derived jet parameters. We find a strong correlation between the total luminosity of broad emission lines and the kinetic luminosity of the jets, which supports the scenario that the accretion process are tightly linked with the radio jets. Moreover we find a significant correlation between the kinetic luminosity and radio extended luminosity. This implies that the emission from the radio lobes are closely related with the energy flux transported through jets from the central part of AGNS.
