Title Constraining the only significant AGN QPO

Description Black hole binaries show high frequency QPOs. These are not well understood but their short timescales imply they must be produced close to the event horizon. Our recent discovery of the first significant AGN QPO gives a unique opportunity to study these in much more detail than is possible in BHB from the .slowed down. AGN QPO lightcurve. A single re-observation of the QPO would show that this is indeed a characteristic feature of this super-Eddington source, but the QPO is transient, not present in a followup snapshot. We propose 7 snapshots of 50ks each (the maximum possible in this AO and the minimum required for a 3 sigma detection) to re-detect the QPO and study its properties.

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.
