Description NGC5548, one of the brightest, most strongly variable and best-studied AGN in X-rays, has only 20 ksec in the XMM GTO programme. We propose a 130 ksec long look. When combined with ongoing RXTE monitoring, this will allow determination of the fluctuation power density spectrum over an unprecedented range of time scales from ~100 to 4x107 sec and measurement of the low frequency break characteristic time scale. NGC 5548 has been claimed to show quasi periodic oscillation; these data will provide a rigorous test. The deep RGS observation will allow the first direct view of its rich spectrum, which includes a strong warm absorber, soft excess and iron line. If we detect rapid variability in these components, we will use cross-correlation analysis to estimate the size.

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.
