MULTIWAVELENGTH TESTS OF THE DUSTY TORUS MODEL FOR SEYFERT-GALAXIES

We present a compilation of emission properties for a sample of 116 Se yfert galaxies based on both previously unpublished data and measureme nts available in the literature. These measurements include fluxes in the emission lines [O III] lambda 5007 and H beta, as well as the infr ared (25-60 mu m), ultraviolet (1450 Angstrom), soft (0.2-4 keV), and hard (2-10 keV) X-ray continua. These data are used to try to distingu ish between isotropic and anisotropic emission properties of Seyfert g alaxies. The distribution functions of [O III] lambda 5007, infrared, and hard X-ray continuum are similar for Seyfert 1's and Seyfert 2's, consistent with these properties being isotropic. The ultraviolet and soft X-ray continua of Seyfert 2's are underluminous relative to the t ype 1's suggesting photons at these energies escape from the central s ource anisotropically. There is a correlation between the ultraviolet continuum and emission-line fluxes in Seyfert 1's consistent with the idea that the central engine is responsible for powering the line emis sion. No such correlation is found for the Seyfert 2's. Instead, the s catter in the plot of ultraviolet continuum versus line emission sugge sts the true nuclear continuum luminosity is not seen at Earth in thes e objects. These properties are consistent with those expected in the dusty torus model.
