Study of X-ray reflection features in a sample of Sy 1s observed by BeppoSAX
Abstract
The ionized disc reflection model of Ross & Fabian is applied to a sample of five Seyfert 1 galaxies observed by BeppoSAX. Good fits were obtained for all the objects in the sample. NGC 4051 and Mkn 335 (usually classified as NLSy 1s) show evidence of a highly ionized accretion disc (xi ~ 350 erg cm s^{-1} and xi \~ 800 erg cm s^{-1}). While NGC 3783 seems to be a ``pure Sy 1'' characterized by a highly ionized accretion disc (xi ~ 500 erg cm s^{-1}). All the sources are consistent with having a face-on disc. The accurate determination of the continuum emission allows us to investigate the spectral variability in the case of Mkn 509.
