| Description | GT- Much of the emphasis in research on AGN in recent years has been in the area of unified models and the tentative estimate of the integrated contribution of Seyfert galaxies to the XRB. Studies with previous missions (e.g. GINGA, ASCA and BeppoSAX) have been severely limited to a handful number of objects and biased towards objects containing hidden Seyfert 1 nuclei. Here, we propose to observe with XMM an optically-selected, distance-limited, sample of Seyfert galaxies. The sample includes all (28) known northern Seyfert galaxies with D&amp;lt;22 Mpc and is the deepest and most complete for zvirgul0. |

| 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. |
