The AGN as a Protostar


Moshe Elitzur (UC Berkeley)

March 3 @ 12:00 PM - 1:00 PM

A variety of observations of Active Galactic Nuclei (AGN) show that the nuclear activity is powered by a central massive black hole that drives radio emitting jets and ionizes surrounding line-emitting clouds. This central engine is surrounded by an obscuring medium, comprised of optically thick dusty clouds in a toroidal configuration. There is no accepted scenario yet for the dynamics behind this complex environment. In this talk I will suggest that we may get our clues from star formation, the other known case of accretion to a point mass, and present observational evidence in support of this suggestion.
