|Title||X-ray Emission from Star-Forming Galaxies and their SuperEddington SourcesSSC_27|
|Author||Dr Michael Watson|
|Description||GT- We propose to observe with EPIC a sample of nearby starbursts including giant extragalactic HII regions and HII galaxies that have previously been studied at various wavelengths and have been detected with ROSAT. The aim of the observations is to determine temperature and metallicity of the diffuse gas, and to investigate the contribution of SNRs and accreting binaries to the emission in the 0.2-10 keV range. These quantities will be studied in conjunction with other important properties like morphology, (starburst) age and metallicity. One important aspect will be a spectral and variability study of a sample of "superEddington" sources in these galaxies that in some cases dominate the X-ray output. To this end, we ask for repeated observations of our targets.|

|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.
