We present a Chandra and XMM-Newton study of X-ray emission from the lobes of 33 classical double radio galaxies and quasars. We report new detections of lobe-related X-ray emission in 11 sources. Together with previous detections, we find that X-ray emission is detected from at least one radio lobe in � 75% of the sample. For all of the lobe detections, we find that the measured X-ray flux can be attributed to inverse Compton scattering of the cosmic microwave background radiation, with…

Mode of accretion in episodic radio galaxies and the dynamics of their outer relic lobes
We present X-ray observations with the X-ray Multi-Mirror Mission Newton (XMM-Newton) telescope of three Double-Double Radio Galaxies (DDRGs). We have detected the core, lobes and the environment of
Inverse-Compton Emission from the Lobes of 3C 353
X-ray emission due to inverse-Compton scattering of microwave background photons by electrons in the lobes of powerful radio galaxies has now been seen in a large number of objects. Combining an
Extended X-ray emission from the z = 4.26 radio galaxy 4C 63.20
We report on deep Chandra X-ray Telescope imaging observations of 4C 63.20, one of the few known radio galaxies at z>3.5. The X-ray counterpart is resolved into a core plus two off-nuclear sources
The xmm-newton detection of diffuse inverse compton X-rays from lobes of the FR II radio galaxy 3C 98
The XMM-Newton observation of the nearby FR II radio galaxy 3C 98 is reported. In two exposures on the target, faint diffuse X-ray emission associated with the radio lobes was significantly detected
An X-ray survey of the 2 Jy sample - II. X-ray emission from extended structures
The 2 Jy sample is a survey of radio galaxies with flux densities above 2 Jy at 2.7 GHz. As part of our ongoing work on the southern subset of 2 Jy sources, in paper I of this series we analysed the
Chandra X-Ray Observations of the Redshift 1.53 Radio-loud Quasar 3C 270.1.
Chandra X-ray observations of the high redshift (z = 1.532) radio-loud quasar 3C 270.1 in 2008 February show the nucleus to have a power-law spectrum, Γ = 1.66 ± 0.08, typical of a radio-loud quasar,
Hard X-Ray Spectrum from West Lobe of Radio Galaxy Fornax A Observed with Suzaku
AbstractAn observation of the West lobe of radio galaxy Fornax A (NGC 1316) with Suzaku is reported. SinceFeigelson et al. (1995) and Kaneda et al. (1995) discovered the cosmic microwave background
XMM-Newton detection of X-ray emission from the compact steep-spectrum radio galaxy 3C 303.1
Using XMM-Newton we detect faint unresolved X-ray emission from the compact steep-spectrum radio galaxy 3C 303.1. We detect a thermal component at kT 0.8 keV, which seems likely to be produced in the
Constraints on the average magnetic field strength of relic radio sources 0917+75 and 1401−33 from XMM–Newton observations
We observed two relic radio sources, 0917+75 and 1401−33, with the XMM–Newton X-ray observatory. We did not detect any X-ray emission, thermal or non-thermal, in excess of the local background level
X-ray measurement of electron and magnetic-field energy densities in the west lobe of the giant radio galaxy 3C 236
X-ray emission associated with the west lobe of the giant radio galaxy, 3C 236, was investigated with the Suzaku observatory, to evaluate the energetics in the lobe. After removing contamination from
