The dynamics of low-power radio jets are largely determined by interactions withthe surrounding X-ray emitting gas. 3-D kinematic models have been constructedusing high-resolution radio data for a small number of nearby FRI radio jets,but require good constraints on the external medium over a large range ofdistances to extract information about jet physical conditions (e.g. totalenergy flux, density, pressure, mass entrainment rate). A combination of XMMmeasurements of group-scale X-ray emission with Chandra measurements of the jetinner regions is required to sample all the necessary physical scales, assuccessfully demonstrated with previous observations. Here we propose to extendthis programme to two lower luminosity radio galaxies, B2 1553+24 and B2 0326+39.

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.
