| 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. |
