Description We propose a 100 ks XMM-Newton observation of J1641, a z=6.047 QSO accreting at a super- Eddington rate (lEdd=1.5). Our exploratory Chandra observation of this object (virgul48 net counts) reveals extremely bright X-ray emission, 9 times brighter than the expectation based on its UV luminosity, in contrast to our knowledge of accretion at high Eddington ratio. Thanks to the extremely bright X-ray emission of the target, the new XMM-Newton observation will collect virgul400 net counts, which is the largest number of X-ray photons for a z>6 QSO, allowing us to constrain tightly the X- ray properties of this QSO, in particular its luminosity and photon index, and to check for variability.

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.
