| Abstract: |
We present the results of a study of the hard X-ray spectra of all the Sy 1 and Sy 2 galaxies as observed with the PDS (15-200 keV) aboard BeppoSAX. The aim of this study is to compare the intrinsic emission of a large sample of Seyfert galaxies (14 Sy1, 10 Sy 1.5 and 22 Compton thin Sy2) to test the unified model according to which Sy1 and Sy2 have the same nucleus. We built the average spectra of the different classes of Sy galaxies in order to compare their spectral properties at energies where absorption effects play no role and where we have a direct access to the central engine. We discuss the differences and common properties of the spectra and present a new vision of the unified model. |
