Scientific paper

We propose exploratory 4 ks observations of ten of the most luminous and optically brightest quasars at z > 4. Our science goals are (1) to determine the X-ray fluxes, X-ray luminosities, optical-to-X-ray slopes, and broad-band spectral energy distributions (SEDs) of these quasars, (2) to constrain X-ray spectral properties using hardness ratios and stacking analyses, (3) to facilitate spectroscopic observations with XMM-Newton, and (4) to lay key groundwork for future high-redshift X-ray efforts with Constellation-X and XEUS. We will obtain supporting optical and near-infrared spectroscopy with the queue-scheduled 8-m Hobby-Eberly Telescope. The proposed project will complement our other studies of z > 4 quasars using Chandra, XMM-Newton, and archival data.
