1999PASP..111....1K The Ultraviolet and Optical Continuum Emission in Active Galactic Nuclei: The Status of Accretion Disks ANURADHA KORATKAR Space Telescope Science Institute, Baltimore, MD 21218; koratkar@stsci.edu AND OMER BLAES Physics Department, University of California, Santa Barbara, CA 93106; blaes@vela.physics.ucsb.edu Received 1998 September 29; accepted 1998 October 2 ABSTRACT. A fundamental component of models of active galactic nuclei (AGNs) is an accretion disk around a supermassive black hole. However, the nature of this accretion disk is not well understood, and current models do not provide a satisfactory explanation of the optical/UV continuum observed in AGNs. In this paper we review the substantial theoretical and observational progress made in the field. We also try to point out future research directions that would be fruitful in trying to obtain a complete, self-consistent model of the continuum-emitting regions.
