A new view of the origin of the radio-loud radio-quiet AGN dichotomy?
Alessandro Capetti, Barbara Balmaverde
Using archival Chandra and HST observations of nearby early-type
galaxies we found a suggestive link between the properties of the
active nucleus and of the host galaxy. Galaxies with a shallow cusp in
their brightness profile are associated with radio-loud nuclei, while
radio-quiet AGN are only hosted by galaxies with steep cusps. The
radio-loud/radio-quiet dichotomy appears to be univocally related to
the core/power-law dichotomy in the host's profiles.
