|Title||Spectral Variability of Seyfert Galaxies|
|Author||Prof Keith Mason|
|Description||GT- We wish to perform long pointings (150 ksec) with XMM at two bright Seyfert 1 galaxies, NGC4051 and Mrk766, in order to measure i) the power spectrum of flux variations down to the shortest scales, ii) the cross correlation of variations at medium X-ray, soft X-ray, UV and optical wavelengths, iii) changes in the spectral shape of the X-ray continuum iv) variations of spectral features such as absorption from partially ionized gas and the fluorescent Fe emission line(s) in response to continuum variations.|

|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.
