| Description | GT- Most galaxies belong to poor groups, and much of the baryonic matter in collapsed objects in the universe resides in the X-ray emitting intragroup medium. The distribution, and thermal and chemical properties of this hot gas provides an ideal laboratory for testing theories of cD galaxy formation and the effects of star-formation-driven feedback on intergalactic matter. We propose to observed three very poor groups with extended X-ray emission peaked on a central bright elliptical galaxy in order to measure the profiles of temperature and abundances of various elements, and decompose these into components associated with the central galaxy and the group as a whole. |

| 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. |
