Extended and Compact X-ray Emission in Powerful Radio Galaxies
نویسندگان
چکیده
We report ROSAT X-ray observations of two powerful radio galaxies. 3C 280 provides evidence for a mixture of unresolved and extended emission, with the latter produced by hot plasma of insufficient pressure to confine the radio lobes and insufficient density for a cooling flow to have begun. 3C 220.3 gives only an X-ray upper limit, but one consistent with our interpretation of the X-ray emission from powerful radio-loud AGNs in terms of obscured and unobscured components. Subject headings: galaxies: active galaxies: individual (3C 220.3, 3C 280) radio continuum: galaxies X-rays: galaxies

Extended 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 ...
متن کاملCompact Radio Cores and Nuclear Activity in Seyfert Galaxies
Using recent high–resolution (<0.1”) radio observations of a large sample of Seyfert galaxies (Roy et al., 1994), we analyze the relations between their compact radio core emission and several nuclear and host galaxy properties (galaxy morphology, optical, infrared, X-ray, extended radio emissions, interaction parameters, and some emission line properties). We apply survival analysis techniques...
متن کاملVlbi Imaging of the X-ray Bright Lobe Hotspot in Pks B2152 699
Wide-field very long baseline interferometric (VLBI) imaging can be used to study the compact radio structures in extended extragalactic radio sources such as starburst galaxies and radio galaxies. Recently, compact radio emission has been detected from the southern lobe hotspot in the nearby, powerful radio galaxy PKS B2152 699, using an array of Southern Hemisphere radio telescopes, resulting...
متن کاملAnisotropic inverse Compton scattering in powerful radio galaxies : the case of 3 C 295
Inverse Compton (IC) scattering of nuclear photons with relativistic electrons in the lobes of powerful radio galaxies and quasars can give detectable extended X–ray emission from the radio lobes if relativistic electrons with a Lorentz factor γ < 300 are present (Brunetti, Setti, Comastri 1997). In general these electrons are not detected since they emit synchrotron radiation at frequencies be...
متن کاملMagnetic Field Strengths in the Hot Spots and Lobes of Three Powerful Fanaroff-riley Type Ii Radio Sources
We have made deep Chandra observations of three powerful Fanaroff-Riley type II (FR II) radio sources: two quasars (3C 263 and 3C 351) and one radio galaxy (3C 330). X-ray emission from hot spots and lobes, as well as from the active nucleus, is detected in each source. We model the hot spots’ synchrotron spectra using VLA, BIMA, and Hubble Space Telescope data. In 3C 263 and 3C 330, the hot sp...
