Scientific paper
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. This would provide us with a novel tool to explore the co-evolution of galaxies and supermassive black holes, and it would open a new path to understand the origin of the radio-loud/radio-quiet dichotomy. We propose to complete the Chandra observations of our sample, as to put these results on a much firmer statistical basis.
