Abstract : Analysis of the radio synchrotron and X-ray inverse-Compton emission from powerful radio loud AGNs allows us to determine their particle acceleration processes and electron energy spectra. We have observed 3C270.1, bright FRII radio galaxy at z = 3.536 using Chandra. Combining these X-ray observations with archival multi-frequency radio observations, we present our preliminary results: The detection of radio jet in X-ray from the most distant radio galaxy ever seen and put constraints on the densities from the radio lobes and thermal emission, if any, from the hot phase of the ambient medium. These results would be crucial to understand the interplay between the ambient medium and the radio galaxy, and describe the properties of the particle energy spectrum in the radio lobe. We would also discuss some of these implications.
