We propose to observe a recently discovered radio-loud quasar at redshiftz=6.82; this quasar is both the most radio-loud and the most radio-luminousquasar known at z>6, and appears to be powered by a supermassive black holeexperiencing super-Eddington accretion. VLA images have revealed an additionalstructure 25 arc seconds (virgul125 kpc, projected) away, potentially indicatinglarge jets associated with the extreme accretion rate. If these jets areinteracting with the Cosmic Microwave Background, which has an energy densitythat scales as (1+z)^4, we expect to see significant extended X-ray emissionaround the quasar. Our proposal will provide the first X-ray observations of aradio-loud quasar at z>6.

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.
