| Abstract | We propose a 60 ks observation of the narrow-line QSO PG 1543+489 at z=0.40. Thesource is characterized by peculiar properties: the OIII emission line has themost extreme value of blueshift among AGN and a blue asymmetry in its profile,indicative of an outflow. This outflow can be related to the high accretion rateof the QSO, as suggested by the presence of an ultra-steep (Gamma=2.8) X-rayslope in a previous short XMM-Newton observation. The same observation revealedthe presence of a relativistic iron K alpha line, whose detailed analysis washowever limited by the poor photon statistics. The large EW of the line (2-3.9keV) suggests the presence of light-bending effects or amplification by microlensing, which can be tested only with a longer XMM-Newton exposure. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
