Scientific paper

Active galaxies are the most powerful engines in the Universe for converting gravitational energy into radiation, and their study at all epochs of evolution is therefore important. Powerful radio-loud quasars and radio galaxies have the added advantage that, since their radio jets need X-ray-emitting gas as a medium in which to propagate, the sources can be used as cosmological probes to trace significant atmospheres at high redshift. The radio emission can be used as a measure of source orientation, and sensitive X-ray measurements, especially when used in combination with multi-wavelength data, can be used to derive important results on the physical structures on a range of sizes from the cores to the large-scale components. In this paper we present new results on a significant sample of powerful radio galaxies and quasars at z > 0.5, drawn from the 3CRR catalogue and selected to sample a full range of source orientation. Using high-quality observations from XMM-Newton and Chandra, we discuss the X-ray properties of the cores, jets, lobes and cluster gas, and, through the incorporation of multi-wavelength data, draw conclusions about the nature of the emission from the different components.
