Description We propose to continue our systematic XMM-Newton and Chandra study of the most distant known quasars, with our goals being to learn about the central power sources and environments of the first quasars to form in the Universe. Here we propose six XMM-Newton spectroscopic observations of quasars with z = 4.09-5.82. We have detected all of our targets in exploratory observations, and they include the X-ray brightest non-blazars known above redshift 4. We will measure the X-ray continuum shape and will study X-ray absorption associated with the quasars. environments. Joint spectral fitting will give further constraints on average X-ray spectral properties. We will also search for clustered X-ray AGN in high-redshift large-scale structure.

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.
