Inverse Compton X – rays from the radio galaxy 3 C 219
We report the results from a Chandra observation of the powerful nearby (z=0.1744) radio galaxy 3C 219. We find evidence for non–thermal X–ray emission from the radio lobes which fits fairly well with a combination of inverse Compton scattering of Cosmic Microwave Background radiation and of nuclear photons with the relativistic electrons in the lobes. The comparison between radio synchrotron a...
متن کاملEvidence for inverse Compton emission in the powerful radio galaxy 3 C 219
Spectral analysis of ROSAT PSPC and ASCA archive data and a recent ROSAT HRI observation of the powerful FRII radio galaxy 3C 219 reveal an absorbed point–like source, coincident with the nucleus, and a non–thermal extended component aligned with the radio structure. The point– like source can be readily interpreted as a hidden quasar in the nucleus, giving further support to the unification sc...
متن کاملInverse Compton X-rays from relativistic flare electrons and positrons
Context. In solar flares, inverse Compton scattering (ICS) of photospheric photons might give rise to detectable hard X-ray photon fluxes from the corona where ambient densities are too low for significant bremsstrahlung or recombination. γ-ray lines and continuum in some large flares imply the presence of the necessary ∼ 100 MeV electrons and positrons, the latter as by-products of GeV energy ...
متن کاملAnisotropic Inverse Compton Scattering in the Galaxy
The inverse Compton scattering of interstellar photons off cosmic-ray electrons seems to play a more important rôle in the generation of diffuse emission from the Galaxy than thought before. The background radiation field of the Galaxy is highly anisotropic since it is dominated by the radiation from the Galactic plane. An observer in the Galactic plane thus sees mostly head-on scatterings even...
متن کاملExtended and Compact X-ray Emission from the Powerful Radio Galaxy 3c 220.1
We report on ROSAT HRI observations of the z = 0.61 radio galaxy 3C 220.1. The X-ray emission from this object consists of an extended component, which we attribute to luminous cluster emission, and a compact central source. The compact component is too bright to be modelled as a cooling flow under some plausible assumptions for the hot gas temperature and distribution; we suggest instead that ...
