Scientific paper

We discuss different aspects of nested bar dynamics and its effect on the gas flow and fueling of Active Galactic Nuclei. Specifically we focus on the dynamical decoupling between the primary and secondary bars and the gas flow across the bar-bar interface. We analyze the nuclear gaseous bar formation when gas gravity can be neglected or when it dominates. Finally, we discuss the possible effect of flat core, triaxial, dark halos on the formation of galactic bulges and supermassive black holes (SBHs) and argue in favor of SBH-bulge-halo correlation.
