GT - We propose to determine whether complex, possibly ionized Fe-K emissionis present in M81, NGC4579 and M51 as suggested by examination ofASCA data. We will constrain the energy of the line centroid and thus resolve whether the line-emitting gas is ionized. The line E.W. will be used as a diagnostic to discriminate between various models for the originof the Fe-K lines. Constraints on the line profiles will be used toindicate the extent of any relativistic line broadening or line complexity.

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.
