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.
