Description The form and evolution of the X-ray luminosity function (XLF) of high z AGN, and hence the importance of black hole accretion in the early universe, is poorly constrained. A combination of deep, multi-colour optical imaging and X-ray data has proved highly efficient in compiling high z AGN samples with well defined selection and minimal incompleteness, and shows that the faint-end slope of the XLF at z=3 is significantly steeper than previously reported. Our current survey still has limited statistics around and above L*, however. The first data release of the CFHTLS Deep Fields provides an opportunity to rectify this. Relatively modest investment of XMM time (~200ks) will provide almost complete X-ray coverage over 4 square deg, enabling us to accurately determine the XLF at z=3-4.

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.
