摘要
XMM-Newton observations of the BAL quasar PHL 5200 revealed that the X-ray emission attributed to the quasar originates from a nearby, optically unidentified radio source. Although visible in X-rays as well the flux from PHL 5200 is by a factor greater than or similar to 20 smaller than previously anticipated. Thus most of the scenarios for a physical interpretation of the BAL phenomenon, based on the apparently unexpected X-ray properties of this quasar have to be revisited. We further discuss the properties of the optically very faint radio source.
