|Title||The Hot ISM of Chemically Unevolved Galaxies|
|Author||Prof Trinh Xuan Thuan|
|Description||Blue compact dwarf (BCD) galaxies are the least chemically evolved gas-rich galaxies in the universe. They are thus excellent laboratories for studying physical processes which occurred in the galaxy formation era, when the gas was metal-deficient. We wish to obtain deep EPIC spectroscopy to study the evolution of the hot phase medium in 3 BCDs, IZw49, Mrk 71 and VIIZw403. The first two BCDs are cometary-like, with propogating star formation along their stellar bodies which allows us to study the time evolution of the hot phase within the same galaxy. The third BCD allows us to study a .blow out., when the supernova energy has disrupted the HI envelope and set up a galactic wind.|

|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.
