| Description | We aim at completing a sample of Seyfert 2s, selected according to the morphology of their nuclear dust. We request 13 AO1 priority C objects. The main goal of the proposal is to verify whether the X-ray absorption in Compton-thin and -thick Seyfert 2 galaxies is associated with different physical media. Preliminary results support the idea that the compact torus may be responsible for the absorption in Compton-thick objects only, whereas the Compton-thin absorbing media could be located at much larger scale, maybe related to the host galaxy rather than to the nuclear environment. We propose to establish the above hypothesis on a firm statistical ground. 115 ks are requested. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
