  The analysis of a sample of 30 isolated spiral galaxies with and without an
AGN results in active and control galaxies having similar bulge and disk
properties (since both samples are selected to match in morphological and bar
classification, they have similar bar percentages). Secondary bars seem also to
be indistinguishable. The central kinematics (both stellar and gas) are also
studied in order to put some constraints on the processes required to fuel
AGNs. Together with previous results, this points to AGNs being an episode of
the life of galaxies, providing that the fuel is available and the accumulation
mechanisms are at work.
