Abstract We propose to extend our systematic X-ray studies of the most distant knownquasars with XMM-Newton spectroscopic observations of six radio-loud quasars(RLQs) at z = 3.63-4.39. Our targets are more representative of the overall RLQpopulation than the small number of highly radio-loud blazars studied at highredshift, and we have detected all targets in exploratory Chandra observations.We will study X-ray absorption in the quasars environments to determine if itis common among typical RLQs at high redshift. We will also measure X-raycontinuum shapes and search for variability, clustered AGN, and X-ray jets.

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.
