|Nature of the cool component in the cD Cluster AWM7
|Dr Tae Furusho
|AWM7 is the 2nd brightest poor cluster of galaxies (with kT le 4 keV) in the sky next to the Centaurus cluster. Based on the spatially resolved spectra of the central cool component, we can unambiguously determine the origin of the cool component and look into its evolution process in the cD type clusters. The cool component of AWM7 is extended and is probably in an early stage of evolution, placing this cluster an important target for the systematic study of the cool-component evolution. The proposed 30 ks observation will also enable us to examine non-uniformity in the spatial distribution of metals, and further to estimate the cusp structure of the gravitational potential which confines the hot-component gas.

|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.
