Extended inverse-Compton emission from distant, powerful radio galaxies.


Abstract (from CDS):

We present Chandra observations of two relatively high redshift FRII radio galaxies, 3C432 and 3C191 (z = 1.785 and 1.956, respectively), both of which show extended X-ray emission along the axis of the radio jet or lobe. This X-ray emission is most likely to be due to inverse-Compton scattering of cosmic microwave background (CMB) photons. Under this assumption, we estimate the minimum energy contained in the particles responsible. This can be extrapolated to determine a rough estimate of the total energy. We also present new, deep radio observations of 3C294, which confirm some association between radio and X-ray emission along the north-east-south-west radio axis and also that radio emission is not detected over the rest of the extent of the diffuse X-ray emission. This together with the offset between the peaks of the X-ray and radio emissions may indicate that the jet axis in this source is precessing.
