Probing the extended emission-line region in 3C 171 with high-frequency radio polarimetry
I present high-frequency polarimetric radio observations of the radio galaxy 3C 171, in which depolarization is associated with an extended emission-line region. The radio hotspots, known to be depolarized at low radio frequencies, become significantly polarized above (observer’sframe) frequencies of 15 GHz. There is some evidence that some of the Faraday rotation structure associated with the ...
متن کاملDetection of Optical Synchrotron Emission from the Radio Jet of 3c 279
We report the detection of optical and ultraviolet emission from the kiloparsec scale jet of the well-known quasar 3C 279. A bright knot, discovered in archival V and U band Hubble Space Telescope Faint Object Camera images, is coincident with a peak in the radio jet ∼0.6 from the nucleus. The detection was also confirmed in Wide Field Planetary Camera-2 images. Archival Very Large Array and ME...
متن کاملX-ray Emission from the Radio Jet in 3c 120
We report the discovery of X-ray emission from a radio knot at a projected distance of 25′′ from the nucleus of the Seyfert galaxy, 3C 120. The data were obtained with the ROSAT High Resolution Imager (HRI). Optical upper limits for the knot preclude a simple power law extension of the radio spectrum and we calculate some of the physical parameters for thermal bremsstrahlung and synchrotron sel...
متن کاملLine source emission modelling
Line source emission modelling is an important tool in control and management of vehicular exhaust emissions (VEEs) in urban environment. The US Environmental Protection Agency and many other research institutes have developed a number of line source models (LSMs) to describe temporal and spatial distribution of VEEs on roadways. Most of these models are either deterministic and/or statistical ...
متن کاملMolecular Gas in 3c 293: the First Detection of Co Emission and Absorption in an Fr Ii Radio Galaxy
The first detection of CO emission in a Fanaroff-Riley Class II (i.e., edge-brightened radio morphology) radio galaxy is presented. Multiwavelength (0.36-2.17 μm) imaging of 3C 293 shows it to be a disk galaxy with an optical jet or tidal tail extending towards what appears to be a companion galaxy 28 kpc away via a low surface brightness envelope. The molecular gas appears to be distributed in...
