The Contribution of the obscuring torus to the x-ray spectrum of Seyfert galaxies: A Test for the unification model

摘要: The presence of an obscuring torus around the nucleus a Seyfert galaxy, as supposed in popular unification scheme, can strongly modify X-ray spectrum for both type 1 and 2 galaxies. We study this problem by means Monte Carlo simulations, finding that, if is Compton-thick, it scatter at small angles significant fraction nuclear radiation, contribute to continuum galaxies above ∼10 keV, fluorescence iron line 6.4 keV. At large inclination column densities, attenuated photoabsorption Compton scattering, while produced have equivalent widths
