Scientific paper

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.
