Scientific paper

I present estimates of black hole accretion rates and nuclear, extended, and total star-formation rates for a complete sample of Seyfert galaxies. I find that black hole growth (measured from the [OIV] 26 micron line) is strongly correlated with nuclear star formation (measured on sub-kpc scales using the 11.3 micron PAH feature), but only weakly correlated with extended star formation in the host galaxy (measured from 24 micron continuum emission). This suggests that the primary difference between low-luminosity and high-luminosity AGNs is the amount of gas present in the central kilo-parsec and supports suggestions of a link between AGN activity and elevated nuclear star formation.
