Description | XMM has been at the forefront of the recent discovery X-ray relativistic reverberation. Short Fe K delays have been observed in seven objects. To advance beyond mere detections, we propose to observe the bright AGN NGC 4151 for 350 ks to directly measure the relativistic transfer function, which encodes the geometry, dynamics and the way space-time alters the path of light through the potential of the black hole. NGC 4151 is the ideal laboratory for such an experiment because of its brightness, variability and the existing reverberation lags. Combing the new and archival data will allow us to measure the Fe K response at many time-scales providing a first direct measurement of the transfer function. XMM is currently the only telescope capable of achieving such a legacy goal prior to Athena. |

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. |
