In a matched sample of Seyfert and quiescent galaxies we simultaneously probethe stellar and molecular gas kinematics from 1 kpc down to 50 pc with the aimof identifying the dynamical processes dictating black hole accretion rates.This first paper compares the global characteristics of a sample of tengalaxies. We find several differences within a radius of 500 pc that arecorrelated with Active Galactic Nucleus (AGN) activity. The Seyferts have: (1)a more centrally concentrated nuclear stellar surface brightness with lowerstellar luminosities beyond a radius of 100 pc, (2) a lower stellar velocitydispersion within a radius of 200 pc, (3) elevated H2 luminosity out to aradius of at least 250 pc, and (4) more centrally concentrated H2 surfacebrightness profiles. These observed differences can be interpreted as evidencefor Seyfert galaxies having a dynamically cold (in comparison to the bulge)nuclear structure composed of a significant gas reservoir and a relativelyyoung stellar population. This structure is undetected (and possibly does notexist) in quiescent galaxies. The presence of such a nuclear structure inSeyfert galaxies provides evidence for inflow of the surrounding interstellarmedium since the nuclear stellar population requires a supply of gas from whichto form. The fueling of a Seyfert AGN is thus associated with the formation ofa dynamically cold component of gas and stars on scales of hundreds of parsecs.
