Faraday rotation and depolarization in the powerful DRAGNs 3C 34, 3C 228 and 3C 340

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...

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...

High Rotation Measure in the Steep Spectrum Quasar 3c 147

We present VLBA polarimetric observations of the steep-spectrum quasar 3C 147 (0538+498) made at four frequencies in the available 5-GHz band, from which we derived milliarcsecond-resolution images of the total intensity, polarization, and rotation measure distributions. The jet extending to the southwest is followed out to a distance of about 200 mas from the core. The jet shows several gentle...

3c 129 : the Gmrt Observations

We present radio maps of the head-tail radio galaxy, 3C 129 at 240 and 610 MHz using the Giant Metrewave Radio Telescope. We have studied in detail the morphology of the source and the distribution of spectral index over the object. We find large-scale spectral steepening along the jet away from the core. Using synchrotron spectral ageing theory, we infer the age (time since particle accelerati...
