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.
