| Description | We propose to extend our systematic X-ray studies of the most-distant known quasars with XMM-Newton spectroscopy of five typical radio-loud quasars (RLQs) at z = 3.98-4.97. Our targets are more representative of the overall RLQ population than the small number of highly radio-loud blazars studied at z virgul 4, and we have detected all targets in exploratory Chandra observations. We will search for X-ray absorption in the quasars. environments to determine if it is common among typical RLQs at the highest redshifts. We will also measure X-ray continuum shapes and search for variability and clustered AGN. |

| 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. |
