چکیده

We present results from global VLBI, VLBA,MERLIN and VLA observations of the quasar 3C395 at 5.0 GHz, global VLBI and VLBA observations at 8.4 GHz, and VLBI test observations at 22.2 GHz. These combinations allow us to obtain radio images with resolutions ranging from 0.2 to 200 milliarcseconds, which show the continuity of the radio structure of 3C395 from parsec to kiloparsec scales. On parsec scales we find clear signs of activity in the compact core and show that the component separations have remained unchanged since epoch 1990.8. On larger scales we confirm the existence of a very sharp bend in the jet at a distance of ∼ 70 mas from the core, the magnitude of which we ascribe to projection effects when the jet is viewed very close to the line of sight. We suggest that 3C395 is a double radio source viewed end-on, with two extended lobes appearing superimposed as a low brightness halo.

Bayesian inference of jet bulk-flow speeds in FRII radio sources

Radio jet and core data for a complete sample of 98 FRII sources with z < 1 are analysed with a Markov-Chain Monte Carlo (MCMC) model fitting method to obtain constraints on bulk-flow speeds in the beam. The Bayesian parameter-inference method is described and demonstrated to be capable of providing meaningful constraints on the Lorentz factor at both kiloparsec and parsec scales. For both jets...

Multi - frequency investigation of the parsec - and kilo - parsec - scale radio structures in high - redshift quasar PKS 1402 + 044

Aims. We investigate the frequency-dependent radio properties of the jet of the luminous high-redshift (z = 3.2) radio quasar PKS 1402+044 (J1405+0415) by means of radio interferometric observations. Methods. The observational data were obtained with the VLBI Space Observatory Programme (VSOP) at 1.6 and 5 GHz, supplemented by other multi-frequency observations with the The observations span a ...

The X-ray and radio jets of quasars on kiloparsec scales

We have observed five quasars (0827+243, 0923+392, 1222+216, 1317+520, and 2209+080) with Chandra at 0.2-8 keV and with the VLA at 5 and 15 GHz. The X-ray emission is detected from all the radio jets except for 0923+392, whose double radio jet only extends out to the edge of the X-ray PSF. We model the spectral energy distribution of the jet features assuming that the X-ray emission originates ...

We have observed the radio source in NGC 3862 (3C264) simultaneously with the EVN and the MERLIN arrays, obtaining detailed images of its radio structure from parsec to sub-kiloparsec scales. 3C264 shows a one-sided jet, with evident variations in its morphological properties with distance. We have analyzed HST optical data of NGC 3862, finding a one-to-one correspondence between radio and opti...

Bendings of radio jets in BL Lacertae objects I: EVN and MERLIN observations

Abstract. Several blazars, and BL Lac objects in particular, show a misalignment between the jet orientation on parsec and kiloparsec scales. Some authors (i.e. Conway & Murphy, 1993) have attempted to explain this behaviour invoking helical jets for misalignment angles around 90, showing how in this case there are interesting implications for the understanding of the medium into which the jet ...
