Scientific paper

We propose to observe four of the most luminous quasars known, which have extremely high accretion rates and are at redshift ~2-3, using XMM-Newton EPIC PN and MOS with a total integration time of 135 ksec. We will obtain accurate measurements of the spectral slope in the quasars' ~1.5-20 keV rest-frame band and look for X-ray variations. Our prime goal is to test whether the X-ray spectral slope is an accretion-rate indicator for all AGN. Steep X-ray spectral slopes may identify our sources as the long sought high-redshift analogs of narrow-line Seyfert 1 galaxies.
