Detection of Iron Emission Line from the Galaxy Cluster Including the Distant Radio Galaxy 3C220.1
We detected an emission line feature at 4 keV in the X-ray spectrum of a sky region including the distant radio galaxy 3C220.1(z = 0.62) obtained with ASCA. The line energy is 6.1 – 7.0 keV (90% confidence) in the rest frame of 3C220.1. Within the present statistics, the observed spectra are consistent with two different models; a non-thermal model consisting of a power-law continuum plus a 6.4...
متن کاملNumerical Modeling of Gamma Radiation from Galaxy Clusters
We investigate the spatial and spectral properties of non-thermal emission from clusters of galaxies at γ-ray energies. We estimate the radiation flux between 10 keV and 10 TeV due to inverse-Compton (IC) emission, π-decay and non-thermal bremsstrahlung (NTB) from cosmic-ray (CR) ions and electrons accelerated at cosmic shocks as well as secondary e generated in inelastic p-p collisions. We ide...
متن کاملThe XMM - Newton view of the broad - line radio galaxy 3 C 120
We present the results of a 127 ks XMM-Newton observation of the broad-line radio galaxy 3C 120 performed simultaneously with RXTE. The data have yielded the highest quality 0.6– 10 keV spectrum of a radio-loud active galaxy ever produced. The time-averaged spectrum is Seyfert-like, with a reflection amplitude R ∼ 0.5, and a neutral Fe Kα line with equivalent width ∼ 53 eV. The line is slightly...
متن کاملA Detailed Study of the Complex Line - Emission Regions in the Radio Galaxy 3 C 34
We present the results of an extensive Fabry-Perot investigation of the extended line-emission gas surrounding powerful radio galaxies. High spatial (< ∼ 1. ′′ 4) and kinematical (400 km s −1) resolution observations of the [O ii]λ3727 emission-line of the powerful, double radio source 3C 34 (z=0.689) are given. We present evidence that anisotropic radiation emanating from a hidden AGN is respo...
متن کاملX - ray spectroscopy of the broad line radio galaxy 3 C 111
We present an ASCA observation of the broad line radio galaxy 3C 111. The Xray spectrum is well described by a model consisting of a photoelectrically-absorbed power-law form. The inferred absorbing column density is significantly greater than expected on the basis of 21-cm measurements of Galactic H i. Whilst this may be due intrinsic absorption from a circumnuclear torus or highly warped accr...
