Constraining the radio jet proper motion of the high-redshift quasar J2134-0419 at z=4.3
K. Perger, S. Frey, K. É. Gabányi +12
To date, PMN J2134-0419 (at a redshift z=4.33) is the second most distant quasar known with a milliarcsecond-scale morphology permitting direct estimates of the jet proper motion.…
The depolarisation properties of powerful radio sources: breaking the radio-power vs. redshift degeneracy
J. A. Goodlet, C. R. Kaiser, P. N. Best +1
We define 3 samples of extragalactic radio sources of type FRII, containing 26 objects in total. The control sample consists of 6C and 7C sources with radio powers of around 10e27…
Annual modulation in the scattering of J1819+3845: peculiar plasma velocity and anisotropy
J. Dennett-Thorpe, A. G. de Bruyn
We present two years of monitoring observations of the extremely variable quasar J1819+3845. We observe large yearly changes in the timescale of the variations (from ~ 1 hour to ~…
Jet reorientation in AGN: two winged radio galaxies
J. Dennett-Thorpe, P. A. G. Scheuer, R. A. Laing +3
Winged, or X-shaped, radio sources form a small class of morphologically peculiar extragalactic sources. We present multi-frequency radio observations of two such sources. We deriv…
EVN observations of low-luminosity flat-spectrum AGNs
A. Caccianiga, M. J. M. Marcha, A. Thean +1
We present and discuss the results of VLBI (EVN) observations of three low-luminosity (P(5 GHz)<10^25 W/Hz) Broad Emission Line AGNs carefully selected from a sample of flat spectr…
A search for distant radio-loud quasars in the CLASS survey: three new radio-selected quasars at z>4
Ignas Snellen, Richard McMahon, Jane Dennett-Thorpe +3
We report on the search for distant radio-loud quasars in the Cosmic Lens All Sky Survey (CLASS) of flat spectrum radio sources with S_5GHz>30 mJy. Unresolved optical counterparts…
