| Abstract | We have identified a relativistic Fe~K emission line in a Chandra spectrum ofthe z=1.055 quasar 3C 287. We request a 56 ksec XMM-Newton observation of 3C 287to obtain a robust detection of the line at the 5-7 sigma level of confidence.Red-shifts of z=1 reach back to an epoch of rapid accretion (and, perhapsspin-up) for black holes. Presently a science driver for XEUS and Con-X, in afew special cases like 3C 287 it is possible to probe the inner accretion flowand black hole spin in distant AGN with XMM-Newton. Our proposed observationwill provide the clearest evidence yet for broad iron lines in this importantevolutionary epoch, facilitating comparisons between present and past black holeaccretion, and will test the X-ray Baldwin Effect. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
