Changing Type Seyferts galaxies and the AGN Unified Model

The aim of the present proposal to test whether the apparent mismatch betweenXray absorption and optical spectral type (attributable to reddening) in someAGN is real or due to changes in he source properties, as predicted by the AGNUnified Scheme. We propose here to complete the quasisimultaneous Xray/Optical observation program of a welldefined sample of Changing TypeSeyferts we started in AO3 and continued to AO6. Besides the simultaneousobservations, we will perform delayed optical spectroscopy to account forpossible time lags between changes in the Xray source and optical. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
