We propose a 300 ksec observation of the canonical mixed-morphology supernovaremnant (MM SNR) W44, designed to localize and map the recently-discoveredover-ionized plasma via its characteristic radiative recombination continuum andenhanced emission lines. XMM-Newton is the only satellite with the effectivearea and spatial resolution needed to effectively find the origin of this plasmacomponent. These results will be combined with our existing efforts to createthree dimensional magnetohydrodynamic (MHD) models of MM SNR and reveal thesource of this intriguing SNR category that may account for much of theturbulence and triggered star formation in molecular clouds.

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.
