The Narrow-Line Seyfert 1 galaxy IRAS13224-3809 shows strong iron-K and L broadlines and high-frequency soft X-ray time lags indicating reflection from theinnermost regions about a rapidly spinning black hole. It persistently varieswith high amplitude changes every 2 to 3 days. The peak frequency and energyspectrum of the lags varies with flux, probably due to changes in size of thecorona. We propose a Very Large Programme consisting of a 1.5Ms observation ofthis object, which will enable the full range of flux levels to be studied,yielding a dynamic picture of the changing height and size of the corona andtransforming our understanding of how luminous black hole accretion operates.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
