Mapping the properties of the low-energy electron population in 3C353

XMMNewton and Chandra observations have shown us that inverseCompton radiationfrom the lobes of powerful radio sources is widely detectable, and its study hasshed new light on the energetics and dynamics of such objects. In principle, thespatial and spectral properties of this radiation offer a unique way to map theproperties of the energetically dominant lowenergy electron population in radiolobes, with important consequences for our understanding of the dynamics ofradio sources on small and large scales. However, this can only be done withbright, nearby targets. We have recently shown that this type of study ispossible in the radio galaxy Pictor A, and here propose to extend it to anothersource, 3C353, which we argue is the best possible target for such observations. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
