Abstract We propose to observe 3 edge-on Milky-Way-like normal spiral galaxies in orderto constrain the presence, properties and physical origin of hot gas in theirhalos, a topic about which relatively little is currently known. Theseobservations will complete our sample of 8 edge-on normal spirals for which wehave a wide range of existing observational data, so that all galaxies will havedeep XMM-Newton and/or Chandra observations. With this sample we can assess therelative contribution to the halo X-ray emission of normal spirals fromSNII-driven galactic fountains, accretion of primordial gas, and SNIa-drivenoutflows. The observations will robustly detect NGC 891-like hot halos, broadlyquantify their properties, and can be used to constrain the efficiency of mechanical energy feedback.

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.
