GT- We propose to observe with EPIC a sample of nearby starbursts includinggiant extragalactic HII regions and HII galaxies that have previously beenstudied at various wavelengths and have been detected with ROSAT. The aim of theobservations is to determine temperature and metallicity of the diffuse gas, andto investigate the contribution of SNRs and accreting binaries to the emissionin the 0.2-10 keV range. These quantities will be studied in conjunction withother important properties like morphology, (starburst) age and metallicity. Oneimportant aspect will be a spectral and variability study of a sample ofsuperEddington sources in these galaxies that in some cases dominate the X-rayoutput. To this end, we ask for repeated observations of our targets.

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.
