Query: JD6 - The Connection between Radio Properties and High Energy Emission
  in AGNs   While observations in the radio band are providing essential information on
the innermost structures of relativistic jets in active galactic nuclei (AGN),
the recent detection by Fermi of gamma-ray emission from many hundreds of
blazars shows that the maximum jet power is emitted at high energies.
Multi-wavelength monitoring observations further allow variability studies of
the AGN spectral energy distributions over 13 orders of magnitude in frequency.
The Joint Discussion offered the possibility for a comprehensive discussion of
advances in the observational domain and stimulated theoretical discussion
about our current understanding of jet physics.
