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…
Methanol Masers as Tracers of Circumstellar Disks
R. P. Norris, S. E. Byleveld, P. J. Diamond +11
We show that in many methanol maser sources the masers are located in lines, with a velocity gradient along them which suggests that the masers are situated in edge-on circumstella…
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…
A 5 GHz Southern Hemisphere VLBI Survey of Compact Radio SOurces - I
Z. -Q. Shen, T. -S. Wan, J. M. Moran +19
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…
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…
VLBI observations of the 6.7 and 12.2 GHz methanol masers associated with NGC 6334F
S. P. Ellingsen, R. P. Norris, P. J. Diamond +12
We present milliarcsecond resolution images of the 6.7 and 12.2 GHz methanol maser emission associated with the well-known star formation region NGC 6334F. The images agree well wi…
