Radio polarimetry of 3C 119, 3C 318, and 3C 343 at milliarcsecond resolution

VLBI polarimetry of the high rotation measure source 3C 119 at 8.4 GHz

We have mapped the distribution of the rotation measure of the CSS source 3C 119 on milliarcsecond scales using VLBA observations obtained at three widely-separated frequencies in the available 8.4-GHz band. The resulting images at frequencies 8.16, 8.52, and 8.86 GHz demonstrate that the material associated with the large integrated rotation measure of the source is concentrated near the brigh...

Session: 3C

morphology or heart or kidney measurements were evident postmortem. At the tissue-bone interface, mean ∆T in vivo (1.27oC) were lower than postmortem (1.68oC) or in phantoms (1.47oC), with reductions 1mm from the focus. At 2mm from the focus, mean ∆T for all groups were approx. 1oC. The highest ∆T in a live animal was 2.92oC.Conclusions: UBM appears not to generate gross biological effects in m...

Time Variable Faraday Rotation Measures of 3c 273 & 3c 279

Multifrequency polarimetry with the VLBA confirms the previously reported timevarying Faraday rotation measure (RM) in the quasar 3C 279. Variability in the RM and electric vector position angle (EVPA) of the jet component (C4) is seen making it an unreliable absolute EVPA calibrator. 3C 273 is also shown to vary its RM structure on 1.5 year time-scales. Variation in the RM properties of quasar...

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 ...
