Abstract Theories of large scale structure formation, reionisation, and AGN evolution can be studied very well via X-ray studies of high-z QSOs, yet the X-ray properties of z>4.5 QSOs are unknown. We propose observations of four QSOs: three ROSAT detected QSOs at 4.5 < z < 5.0, and the most distant known QSO at z=6.28. We will use XMM data of a z=6.28 QSO to gain crucial insights into the epoch of reionisation, and use the black hole properties to constrain different models predicting when structures first form. Together with X-ray spectra of the 3 ROSAT QSOs, we will examine the evolution of AGN X-ray spectra at high redshifts. Using extensive data already obtained at other wavelengths we will examine models for starburst and QSO triggering in AGN at high-z.

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.
