Beyond the Unification Models in AGN: the BLR in the X-rays

Stefano Bianchi, Università degli Studi di Roma Tre

Different flavors of the Unification Model have been largely successful in explaining most of the complex phenomenology observed in active galactic nuclei (AGN). However, several deviations from the standard scenario have been found, requiring a new view of the role of other parameters, besides the line of sight to the object. In this talk, we will present some recent results on the X-ray 'activity' of the broad line region (BLR), which appears to be an important absorbing or emitting medium also in this energy band, and may be completely absent in some sources.
