Description Giant radio sources (GRSs) raise several important questions related to their confinement and evolution and the properties of the IGM they inhabit. We request to observe two radio galaxies, 3C46 and 3C457, with {it XMM} to image and determine the spectra of the X-ray emission towards addressing some of these questions. The detection of inverse-Compton emission from the radio lobes will enable us to estimate lobe pressures. We will also determine any X-ray emission from a hot-gas environment, and thus understand the properties of the external medium and the confinement of the radio lobes. These observations will provide insights towards using GRSs as cosmological probes and also understanding the evolution of magnetic fields and energy densities with age.

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.
