Extended coronae around massive spiral galaxies is a key prediction of galaxyformation theory. There are very few such galaxies in the local Universe andeven fewer deep X-ray observations of them. We propose to observe 5 luminous,fast rotating, isolated, SF quiescent, and massive spiral galaxies with a totaleffective exposure of 337ks with XMM-Newton. When combined with archival X-rayobservations of 4 other galaxies, the proposal will enable us to compile amini-sample optimized to constrain the mechanisms responsible for establishingthe hot CGM. We will compare radial distributions of coronal properties to thestate-of-the-art hydrodynamical simulations, measure the total baryon content,and establish scaling relations of the coronal and other galaxy properties.

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.
