Description We have identified a relativistic Fe~K emission line in a Chandra spectrum of the z=1.055 quasar 3C 287. We request a 56 ksec XMM-Newton observation of 3C 287 to 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, perhaps spin-up) for black holes. Presently a science driver for XEUS and Con-X, in a few special cases like 3C 287 it is possible to probe the inner accretion flow and black hole spin in distant AGN with XMM-Newton. Our proposed observation will provide the clearest evidence yet for broad iron lines in this important evolutionary epoch, facilitating comparisons between present and past black hole accretion, and will test the X-ray Baldwin Effect.

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.
