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

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.
