Abstract GT- Most galaxies belong to poor groups, and much of the baryonic matter incollapsed objects in the universe resides in the X-ray emitting intragroup medium. The distribution, and thermal and chemical properties of this hot gasprovides an ideal laboratory for testing theories of cD galaxy formation and theeffects of star-formation-driven feedback on intergalactic matter. We propose toobserved three very poor groups with extended X-ray emission peaked on a centralbright elliptical galaxy in order to measure the profiles of temperature andabundances of various elements, and decompose these into components associatedwith the central galaxy and the group as a whole.

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.
