Measurements of the properties of gravitational lenses have the power to tell us what sort of universe we live in. The brightest known radio Einstein ring/gravitational lens PKS 18…
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…
