| Abstract | 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 (~125 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. |
