Abstract

We model the spectral energy distribution of the type 1 Seyfert galaxies,\nfitting data from simultaneous optical, UV, and X-ray monitoring observations.\nWe assume a geometry consisting of a hot central Comptonizing region surrounded\nby a thin accretion disk. The properties of the disk and the hot central region\nare determined by the feedback occurring between the hot Comptonizing region\nand thermal reprocessing in the disk that, along with viscous dissipation,\nprovides the seed photons for the Comptonization process. The constraints\nimposed upon this model by existing multiwavelength data allow us to derive\nlimits on the central black hole mass, the accretion rate, and the radius of\nthe transition region between the thin outer disk and the geometrically thick,\nhot inner region in these objects.\n
