As the largest and most energetic single objects in the Universe, giant radiogalaxies (GRGs), are of particular interest as they are less common but extremeexamples of radio source evolution. No unified model has emerged to explain theproperties of this extreme class of radio galaxies. Previous studies of GRGs aremostly at radio and optical bands, and there is a lack of systematic study ofGRGs in X-rays. As the energetic radio jets of GRGs extend outwards, theyinteract with the surrounding medium. We select a complete sample of nearby GRGsand propose new XMM observations to complete the X-ray coverage of the sample tostudy the X-ray properties of GRGs and their environments, which helps tounderstand the processes responsible for the formation and evolution of GRGs.

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.
