We present narrow band imaging of the [OIII] 5007 Å component for 12 disk-dominated galaxies hosting luminous, unobscured AGN with spectrally confirmed outflows. These massive galaxies’ formation histories are dominated by secular processes and thus provide a unique opportunity to study how inflows from secular processes fuel significant growth of black holes in the absence of significant mergers. We have constrained this contribution from secular processes by using the luminosity and extent of the [OIII] 5007 Å outflow in the narrow band images to measure the rate of mass loss in outflows from the central AGN of these disk-dominated galaxies. By combining these measurements with spectroscopically derived data constraining the black hole accretion rates, we have placed a limit on the total inflow rate to the centre of these galaxies. This technique offers the promise of directly measuring the black hole growth that is occurring in present-day systems evolving solely via secular evolution.
