Magnetic field strengths in the hotspots and lobes of three powerful FRII radio sources
We have made deep Chandra observations of three powerful FRII radio sources: two quasars (3C 263 and 3C 351) and one radio galaxy (3C 330). X-ray emission from hotspots and lobes, as well as from the active nucleus, is detected in each source. We model the hotspots' synchrotron spectra using VLA, BIMA and Hubble Space Telescope data. In 3C 263 and 3C 330, the hotspots' X-ray emission is at a le...
متن کاملLowering Inferred Cluster Magnetic Field Strengths - the Radio Galaxy Contributions
We present a detailed examination of the relationship between the magnetic field structures and the variations in Faraday Rotation across PKS1246−410, a radio source in the Centaurus cluster of galaxies, using data from Taylor, Fabian and Allen. We find a significant relationship between the intrinsic position angle of the polarization and the local amount of Faraday Rotation. The most plausibl...
متن کاملRadio spectrum evolution and magnetic field in extreme GPS radio sources The case of RXJ 1459 + 3337
Aims. The knowledge of the properties of the youngest radio sources is very important in order to trace the earliest phase of the evolution of the radio emission. RXJ1459+3337, with its high turnover frequency (∼ 25 GHz) provides a unique opportunity to study this class of extreme objects. Methods. High-sensitivity multi-frequency VLA observations have been carried out to measure the flux-densi...
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...
متن کاملPolarisation in CSS/GPS radio sources
The polarisation properties of the intrinsically small (< 20 kpc) radio sources are briefly discussed. At centimetric and decimetric wavelengths, substantial polarised emission is often detected in quasars and, at a lower level, in radio sources identified with galaxies with projected linear sizes in excess of a few kpc. The projected linear size at which some polarised emission is detected dec...
