Beschreibungen/Notizen

• We have analysed the NRAO Very Large Array Sky Survey and Sydney University Molonglo Sky Survey data at 1.4 GHz and 843 MHz for a well-defined complete sample of hard X-ray AGN observed by INTEGRAL. A large number (70/79) of sources are detected in the radio band, showing a wide range of radio morphologies, from unresolved or slightly resolved cores to extended emission over several hundreds of kpc scales. The radio fluxes have been correlated with the 2–10 keV and 20–100 keV emission, revealing significant correlations with slopes consistent with those expected for radiatively efficient accreting systems. The high-energy emission coming from the inner accretion regions correlates with the radio emission averaged over hundreds of kpc scales (i.e. thousands of years).
