| Abstract | Giant radio galaxies (GRGs), whose lobes can extend to megaparsec scales, arerarely seen in the centers of galaxy clusters, but in these rich environmentsthey raise important questions for AGN feedback models. With most of the energyof the jets dissipated in lobes far outside the cool core, do such systemsrepresent a failure mode of feedback? If not, how do these sources maintain thethermal balance of the ICM? As only a handful of cluster-central GRGs havemodern X-ray data, we propose XMM snapshot observations of 11 GRGs inoptically-identified brightest cluster galaxies, to confirm the presence of ahot ICM, ascertain its basic properties and establish its morphology, and wherepossible determine the thermodynamic state of the cluster core. |

| 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. |
