Scientific paper

A campaign of simultaneous X-ray and optical observations of unabsorbed Seyfert 2s has already proved successful in the AO-5,leading to the discovery of the first 'true' Seyfert 2 without broad line region.We therefore intend to pursue our strategy,proposing to observe with XMM-Newton a sample of `bona-fide' Seyfert 2 galaxies with no X-ray absorption.The selected sources are a conservative subsample taken from the Panessa & Bassani (2002) sample,including only Seyfert 2s where no column density in excess of the Galactic one has ever been observed in the X-rays,within sensitive limits.The primary goal of this proposal is to find more objects unabsorbed in the X-rays and without broad optical lines,which represent a serious challenge to simple AGN Unification Models.
