| Description | X-ray reverberation shows that the corona is compact, within 10 gravitational radii of the central black hole, and irradiates a disc that extends down to or near the ISCO. However, these results appear in tension with recent Swift disc reverberation results, where the time delay between X-rays and UV/optical is much larger than expected from the standard reprocessing model in which a compact corona irradiates and thermalizes a thin accretion disc. In order to explain these disc reverberation results, two suggestions have been made\: either (1) the thin disc is truncated with a hot inner flow or (2) absorption and scattering from the broad line region affect the time lag measurements. Neither of these two scenarios can be properly tested with Swift alone. XMM-Newton is required. |

| 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. |
