Abstract | Blue compact dwarf (BCD) galaxies are the least chemically evolved gas-richgalaxies in the universe. They are thus excellent laboratories for studyingphysical processes which occurred in the galaxy formation era, when the gas wasmetal-deficient. We wish to obtain deep EPIC spectroscopy to study the evolutionof the hot phase medium in 3 BCDs, IZw49, Mrk 71 and VIIZw403. The first twoBCDs are cometary-like, with propogating star formation along their stellarbodies which allows us to study the time evolution of the hot phase within thesame galaxy. The third BCD allows us to study a blow out, when the supernovaenergy has disrupted the HI envelope and set up a galactic wind. |

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. |
