Scientific paper

We propose to obtain a 45ks X-ray spectrum of SDSSJ2125-0813 - the most luminous radio quiet quasar that shows signs of accretion disk emission in the optical. A short exploratory Chandra observation of this object revealed tentative evidence for an unusually strong, ionized, broad Fe Ka line combined with little or no intrinsic absorption. The proposed XMM-Newton observation will confirm or refute the presence of a relativistic Fe Ka line, the first such line to be detected in a double-peaked emitter. Alternatively, the detection of a strong narrow line will provide a rare example of strong Fe Ka emission in an active galaxy with quasar-like luminosity.
