|Title||COMPLETING THE X-RAY CENSUS OF NEARBY SEYFERT GALAXIES: OUR HIDDEN NEIGHBOURS|
|Author||Dr IAN GEORGE|
|Description||Consideration of the CfA sample of Seyfert galaxies reveals the suprising fact that only half the sample, well studied at most wavelengths, has been observed in the X-ray regime. It is likely these are absorbed sources, and it is important to observe these with XMM to redress our picture of low-z AGN. While much recent work has focussed on obscured AGN at high-z, obscured local sources are an important and neglected part of the luminosity function. These local sources also offer the opportunity to observe a level of detail in the X-ray spectra which is currently impossible to study in high-z sources. XMM observations of local Seyferts complement those at other wavebands & test unification schemes. These sources may also hold secrets undetectable in the more distant counterparts.|

|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.
