| Description | We propose deep XMM obs. of 3 edge on galaxies with newly detected radio halos: NGC4700, NGC7090 and NGC7462. Due to their galaxy scale halos, they are prime candidates for studies of the hot ionized medium at high latitudes above the disk plane. Compared to other galaxies already observed by XMM, these have the advantage of being undisturbed, without active AGNs, providing the chance to study the nature of hot gas in their halos and its dependence on the star formation activity in the underlying disks. Metal abundance analyses will tell whether the gas is predominantly produced by SNIa or SNII, thus testing different scenarios of the chemical enrichment of the ISM and IGM. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
