GT-We propose to obtain EPIC and simultaneous RGS observations of 2 radioloud X-ray luminous quasars with redshifts of 4.30 and 4.72. Both quasarshave already been studied with ASCA and thus a direct comparison betweenXMM and ASCA can be made for calibration purposes. We shall compare theradio to X-ray properties of radio loud quasars at the highest redshiftspossible with the large number of well studied objects at lower redshiftsin an effort to determine how their properties evolve with cosmic time inan effort to constrain black hole formation mechanisms. The mainastrophysical aims are AGN astrophysics and the detection of eitherintrinsic or extrinsic absorption in the QSOs.

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.
