GT- Starburst galaxies are not closed systems; hot gas is seen escaping fromstarburst regions in a galactic wind. However only a few percent of galaxiesshow such high activity. What happens in typical spiral galaxies? Halos ofhot gas have been detected above the discs of normal spiral galaxies withROSAT, and there is a suggestion of weak outflows in several cases.We propose to use the EPIC spectral imagers to examine a small sample of highinclination spirals which show such plumes, in order to establish theexistence of weak galaxy winds, to measure their properties, and to map theproperties of hot galactic coronae in detail.

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.
