|Title||Radio source ageing and the quenching of cooling cores in clusters|
|Author||Dr Elena Belsole|
|Description||We propose to complete the high-quality X-ray observations of a sample of 35 intermediate-redshift bright galaxy clusters by observing 4 with XMM-Newton. The sample is unbiased in X-ray morphology and radio-source content, and is of sufficient size to permit us to address the extent to which cooling flows are halted by mechanical energy injected by radio sources, and if the dynamical state of the cluster gas correlates with the radio environment. This will be achieved by comparing the X-ray-derived temperature, entropy and pressure structures with the energy contents, ages and distributions of the radio-source components within the clusters.|

|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.
