Structures of the magnetoionic media around the FR I radio galaxies 3C 31 and Hydra A
R. A. Laing, A. H. Bridle, P. Parma +1
We use high-quality VLA images of the Fanaroff & Riley Class I radio galaxy 3C 31 at six frequencies in the range 1365 to 8440MHz to explore the spatial scale and origin of the rot…
Multifrequency VLA observations of the FR I radio galaxy 3C 31: morphology, spectrum and magnetic field
R. A. Laing, A. H. Bridle, P. Parma +4
We present high-quality VLA images of the FR I radio galaxy 3C 31 in the frequency range 1365 to 8440 MHz with angular resolutions from 0.25 to 40 arcsec. Our new images reveal com…
The inner jet of radio galaxy NGC 315 as observed with Chandra and the VLA
D. M. Worrall, M. Birkinshaw, R. A. Laing +2
We present Chandra X-ray results for the jet, nucleus, and gaseous atmosphere of NGC 315, a nearby radio galaxy whose jet kinematics are known through deep radio mapping. Diffuse X…
A relativistic model of the radio jets in 3C 296
R. A. Laing, J. R. Canvin, A. H. Bridle +1
We present new, deep 8.5-GHz VLA observations of the nearby, low-luminosity radio galaxy 3C 296 at resolutions from 0.25 to 5.5 arcsec. These show the intensity and polarization st…
Faraday rotation variations along radio jets: the magnetic field in galaxy and group halos
R. A. Laing, J. R. Canvin, W. D. Cotton +2
Our modelling of FR I radio jets as decelerating, relativistic flows allows us to derive their orientations accurately. We present images of Faraday rotation for two of these these…
A relativistic model of the radio jets in NGC 315
J. R. Canvin, R. A. Laing, A. H. Bridle +1
We apply our intrinsically symmetrical, decelerating relativistic jet model to deep VLA imaging of the inner 140 arcsec of the giant low-luminosity radio galaxy NGC 315. An optimiz…
