Description We propose for a 75ksec XMM-Newton observation of the Type 1 AGN AXJ0447-0627. A short 20ksec observation revealed the presence of a bright and prominent set of lines in the Fe rest frame energy range. This set of lines could be described either as 5 narrow Gaussian line, which could be produced by a medium far from the central source, or as a combination of relativistic (from a ionized accretion disk) and non relativistic (emitted by neutral matter distant from the black hole) Fe lines. In AXJ0447-0627 there is an observed property that makes this object unique and deserve further attention: the very high EW of this complex of lines (~2 keV).

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
