The BeppoSAX X-ray view of reflection-dominated Seyfert galaxies Original Research Article

We present new results from BEppoSAX observations of reflection-dominated Seyfert galaxies, and namely: 1) the Compton-thick Seyfert 2 NGC 1068 and Circinus Galaxy; 2) the Seyfert 1 NGC 4051, whose nucleus was observed on May 1998 to have switched off, leaving only a residual reflection component as an echo of its past activity. Our main focus in this paper is on the soft X-ray continuum properties and on the X-ray line spectroscopy.
