Scientific paper

We propose XMM-Newton observations of 6 Seyfert 1.8 and 1.9 galaxies from our approved Spitzer program that will obtain the mid-IR spectra of these AGN. We will use the EPIC spectra to characterize the absorption components and determine their hydrogen column densities in the line of sight to the X-ray emission sources. From the X-ray determinations of gas column densities and global constraints (temperatures, sizes) on the circumnuclear dust regions derived from the Spitzer spectra, we will test the clumpy torus model, and the idea that Seyfert 1.8 and 1.9 galaxies are viewed at intermediate angles with respect to the torus axis. We will obtain groundbased optical and near-IR spectra as well, to measure the dust/gas ratio in the torus.
