Scientific paper
We will obtain ACIS-S spectra of quasars at high redshifts to investigate their: emission spectra to ~30keV (rest); Fe-K emission; low energy cut-offs. A search for extended emission around the quasars will limit any hot atmosphere associated with the surrounding galaxy/cluster in formation. PKS2126-158 is the brightest of the absorbed high z quasars. HE1104-1805 is a radio quiet quasar lensed to be bright. The lens contains a damped Lyman-alpha absorber that should affect the X-ray spectrum, and the two lens components are readily resolved by AXAF at 3 arcsec separation.
