The AGN as a Protostar

Abstract

The 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 torus, comprised of optically thick dusty clouds in a rotating 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.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
