A sample of southern Compact Steep Spectrum radio sources: The VLBI observations
A. Tzioumis, E. King, R. Morganti +19
A small sample of 7 southern Compact Steep Spectrum (CSS) radio sources has been selected as part of the study of a larger flux-limited complete sample of radio sources. High resol…
A 5-GHz Southern Hemisphere VLBI Survey of Compact Radio Sources - II
Z. -Q. Shen, T. -S. Wan, J. M. Moran +20
We report the results of a 5-GHz southern-hemisphere snapshot VLBI observation of a sample of blazars. The observations were performed with the Southern Hemisphere VLBI Network plu…

We report the results of a 5 GHz southern hemisphere VLBI survey of compact extragalactic radio sources. These observations were undertaken with the SHEVE array plus Shanghai stati…
Interstellar Broadening of Images in the Gravitational Lens PKS 1830-211
D. L. Jones, R. A. Preston, D. W. Murphy +8
The remarkably strong radio gravitational lens PKS 1830-211 consists of a one arcsecond diameter Einstein ring with two bright compact (milliarcsecond) components located on opposi…
Discovery of a Sub-Parsec Radio Counterjet in the Nucleus of Centaurus A
D. L. Jones, S. J. Tingay, D. W. Murphy +22
A sub-parsec scale radio counterjet has been detected in the nucleus of the closest radio galaxy, Centaurus A (NGC 5128), with VLBI imaging at 2.3 and 8.4 GHz. This is one of the f…
