Discordant optical and X-ray classification of AGN
  To provide insight into the apparent mismatch between the optical and X-ray
absorption properties observed in 10-30 % of Active Galactic Nuclei (AGN), we
have conducted a detailed study of two X-ray unabsorbed AGN with a type-2
optical spectroscopic classification. In addition to high quality X-ray
spectroscopic observations, that we used to determine both the AGN luminosities
and absorption, we have a VLT/XSHOOTER UV-to-near-IR high resolution spectrum
for each object, that we used to determine the AGN intrinsic emision corrected
for both contamination from the AGN hosts and extinction. Our analysis has
revealed that the apparent mismatch is provoked by galaxy dilution. We dilution
of two AGN with extreme properties: one of them has an intrinsically very high
Balmer decrement while the other lies in a galaxy more massive than expected.
