Description XMM observations have shown that relativistically-broadened iron-K lines and reflection features are common in the spectra of Seyfert 1 galaxies. These offer a means to understand the inner working of accreting black holes, which are the most powerful persistent sources in the Universe. Our XMM observation of the NLS1 galaxy 1H0707-495 shows broad iron-L and K emission which confirm the reflection model. The combination of high soft X-ray count rate in the iron-L band and long exposure has enabled us to measure X-ray reverberation of 30s for the first time. Here we propose long observations of a similar exceptional object, IRAS 13224-3809, which shows extreme spectral features and variability. Long exposures on such objects enables us to take accreting black hole studies to the next level.

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.
