Description We propose to pursue a systematic XMM spectroscopic survey of all known bright (S_5GHz gt 90mJy) radio-loud quasars above a redshift of 4. The proposed sample consists of 6 new radio-loud quasars with redshifts above 4, The XMM observations, combined with the results from the previously observed 4 objects, will address the basic questions concerning the soft X-ray spectral flattening effect as found previously (e.g. Yuan et al. 2000, Fabian et al. 2001). The results are expected to help to discriminate the models of intrinsic flattening and X-ray absorption and, if the latter, will yield insight about the nature of the possible obscuring matter associated with radio-loud quasars in the early Universe.

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.
