We propose XMM-Newton observations of a well-defined sample of face-on spiralgalaxies for which Chandra measurements are already available. The combineddatasets will provide an unprecedented resource for the comparative study of thehigh energy properties of spiral galaxies over a wide range of Hubble type.Issues to be addressed include the distribution, physical state and energeticsof the hot ISM and the spectral and temporal characteristics of the mostluminous discrete sources. We will also investigate the links between X-rayemission and current/recent episodes of star-formation.

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.
