The Stellar Populations in the Central 10pc of Seyfert 2 Nuclei
Marc Sarzi, Joe Shields, Rick Pogge, Paul Martini

Building on previous work on low-luminosity active galactic nuclei, I will present a study of the stellar populations in the very central 10 parsecs of a sample of 19 Seyfert-2 galaxies. The analysis is based on HST-STIS spectra and on a carefull separation of gas emission and the stellar continuum, featuring state-of-the-art stellar population models and also the inclusion of a featureless AGN continuum and of dust extinction. I will discuss our findings on the age, metallicity and abundance of alpha elements of the nuclear populations of these galaxies in the context of the AGN-starburst connection, the formation of galactic nuclei, and the fuelling of supermassive black holes.
