Scientific paper

We propose to observe the highly X-ray luminous z=3.395 radio galaxy B2 0902+343 detected by us with Chandra. The unresolved X-ray source is centred on the active nucleus and has a flat hard spectrum consistent with a flat power-law of photon index 1.1 with intrinsic absorption of 8e22 cm^-2, and an intrinisic 2-10 keV luminosity of 3e45 erg/s. More complex models such as reflection are plausible and would increase the intrinsic luminosity inferred. We expect to detect a significant iron line produced in the source by fluorescence. Soft X-ray XMM data will also measure or constrain the luminosity of any thermal emission from the hot magnetized medium responsible for the high Faraday rotation measures seen in the radio source.
