We propose deep XMM observations of a QSO at z=6.41. This QSO has one of thehighest redshifts currently known, and is the most luminous and massive objectknown at z=6 or greater. Furthermore, unlike any other QSO at these redshifts,this QSO is detected in the sub-mm, indicating that the host galaxy is stillforming. We will combine the X-ray and sub-mm data to obtain the first clearpicture of the formation of a QSO and its host galaxy at the epoch ofreionization. This picture will be used to study the onset and speed ofreionization, to test competing large-scale structure models, and to examine theearliest formation stages of the first massive structures in the Universe.

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.
