Description | Reverberation time lags have been observed in several AGN. The iron line responds to changes in the illuminating continuum with a delay comparable to the light crossing time a few gravitational radii from the black hole. Objects so far with iron K reverberation have broad relativistic lines with strong red wings, supporting their origin in relativistic reverberation. Not all observed AGN however have broad Fe K lines with strong red wings. If the relativistic reverberation hypothesis is correct, objects with a relatively narrow, but relativistic, Fe K lines should show longer delays and narrower lag-energy profiles. Here we propose to observe NGC 5506 to directly test this hypothesis. The new data will provide constraints on the black hole spin independently from spectroscopy and timing. |

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. |
