SNV's Research Interests
Active Galactic Nuclei, AGN, are the centres of some galaxies which emit tremendous amounts of non-stellar radiation. Such radiation is believed to be generated by the accretion of matter--gas and stars--onto supermassive black holes. This intense radiation has profound effects on gas and stars in the circumnuclear environment of these galaxies. There are numerous members of the AGN family, including relatively nearby Seyfert galaxies and the more distant quasars. Of particular interest to me is determining an accurate census of black hole accretion in the nearby Universe, understanding the origin of activity in Seyfert galaxies, and more generally, how the AGN phenomena evolves with time.
