Abstract

The accretion-ejection mechanism acting in Active Galactic Nuclei (AGN) is one of the main astrophysical open issues, being connected to the role of AGN feedback in galaxy formation evolution studies. The X-ray emission in AGN, associated with the accretion flow, is strongly coupled with the radio emission, associated with a jet. Strong correlations between the X-ray and the radio luminosities are found both in radio-loud (RL) and in radio-quiet (RQ) AGN, despite the fact that in RQ AGN jets are often absent or very weak. For a well defined and complete INTEGRAL RQ AGN sample we have found a strong correlation between the 20-100 keV and the radio luminosity. Black hole mass estimates for half of the sample sources allow us to compute the "fundamental plane of black hole activity", sampling the high luminosity/high accretion rate parameter space.
