| Abstract | We aim at completing a sample of Seyfert 2s, selected according to themorphology of their nuclear dust. We request 13 AO1 priority C objects. The maingoal of the proposal is to verify whether the X-ray absorption in Compton-thinand -thick Seyfert 2 galaxies is associated with different physical media.Preliminary results support the idea that the compact torus may be responsiblefor the absorption in Compton-thick objects only, whereas the Compton-thinabsorbing media could be located at much larger scale, maybe related to the hostgalaxy rather than to the nuclear environment. We propose to establish the abovehypothesis on a firm statistical ground. 115 ks are requested. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
