A Search for Water Maser Emission in Southern AGN and Star Forming Galaxies -- Discovery of a Maser in the Edge-on Galaxy IRASF01063-8034

L. J. Greenhill, S. P. Ellingsen, R. P. Norris +7

We report the cumulative results of five surveys for water maser emission at 1.35 cm wavelength in 131 active galactic nuclei (AGNs) and star-forming galaxies, conducted at the Par…

Extremely Rapid Variations of Water Maser Emission from the Circinus Galaxy

L. J. Greenhill, S. P. Ellingsen, R. P. Norris +4

The water maser lines in the nucleus of the Circinus galaxy vary on time scales as short as a few minutes, at least two orders of magnitude less than for other Galactic or extragal…

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…
