| Abstract | PMN 0525-336 is a powerful radio-loud quasar at z=4.41. Its high X-raybrightness of 1e-12 erg/s/cm2 in the 2-10 keV band and low Galactic column density of 2.2e20 mean that EPIC pn will give an excellent spectrum over the 0.5-65 keV rest band. It is one of a small set of blazars at z>4 which show extreme properties, possibly as a result of their high power. We propose to observe it with XMM to determine the spectral curvature and to search for intrinsic absorption (the host galaxy is likely still forming). |

| 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. |
