We propose to make deep RGS observations of three low redshift clusters in orderto make definitive statements about the range of temperature in the clusters andthe level and spatial distribution of cooling. All three clusters have coolcores, short central cooling times and central radio sources making bubbles. Thetargets all show FeXVII emission lines, and as they are nearby we are able tospatially resolve the innermost region where the feedback must originate. Theseobservations will exploit the unique capability of the RGS, and build on one ofXMM.s major discoveries.

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.
