The dynamics of low-power radio jets are largely determined by interactions withthe surrounding X-ray emitting gas. Our previous Chandra and XMM-Newtonobservations of radio-galaxy environments have demonstrated the importance ofX-ray observations in constraining the physical conditions and dynamics of radiogalaxies on small and large scales. Here we propose to observe two of thebest-studied FRI radio galaxies, for which we have high-resolution radio dataand three-dimensional kinematic models, with the aim of measuring density andpressure in the X-ray emitting environment so as to constrain the jet models, toallow physical properties of the jets to be determined, and to investigatelarge-scale jet/environment interactions.

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.
