A Warped Accretion Disk and Wide Angle Outflow in the Inner Parsec of the Circinus Galaxy
L. J. Greenhill, R. S. Booth, S. P. Ellingsen +7
We present the first VLBI maps of H2O maser emission (lambda 1.3cm) in the nucleus of the Circinus Galaxy, constructed from data obtained with the Australia Telescope Long Baseline…
Spectral, polarisation and time-lag properties of GRS 1915+105 radio oscillations
R. P. Fender, D. Rayner, S. A. Trushkin +4
We report high sensitivity dual-frequency observations of radio oscillations from GRS 1915+105 following the decay of a major flare event in 2000 July. The oscillations are clearly…
First Results from the COLA Project- the Radio-FIR Correlation and Compact Radio Cores in Southern COLA Galaxies
E. A. Corbett, R. P. Norris, C. A. Heisler +5
We present the first results from the COLA (Compact Objects in Low-power AGN) project which aims to determine the relationship between one facet of AGN activity, the compact radio…
Bipolar outflows in OH/IR stars
Albert A. Zijlstra, J. M. Chapman, P. te Lintel Hekkert +5
We investigate the development of bipolar outflows during the early post-AGB evolution. A sample of ten OH/IR stars is observed at high angular resolution, including bipolar nebula…
Cold gas and star formation in a merging galaxy sequence
Antonis Georgakakis, Duncan A. Forbes, Ray P. Norris
We explore the evolution of the cold gas and star-formation activity during galaxy interactions, using a merging galaxy sequence comprising both pre- and post-mergers. Data for thi…
Radio-Luminous Southern Seyfert Galaxies. I. Radio Images and Selected Optical/Near-Infrared Spectroscopy
M. A. Bransford, P. N. Appleton, C. A. Heisler +2
This is the first of two papers in which a study is made of a sample of 12 southern radio-luminous Seyfert galaxies. Our aim is to investigate possible correlations between radio m…
A comprehensive search for extragalactic 6.7-GHz methanol masers
C. J. Phillips, R. P. Norris, S. P. Ellingsen +1
We have used the Australia Telescope Compact Array (ATCA) to search for 6.7-GHz methanol maser emission towards 87 galaxies. We chose the target sources using several criteria, inc…
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…
A Survey of the Galactic Plane for 6.7-GHz Methanol Masers I: l = 325.0 - 335.0 ; b = -0.53 - 0.53
S. P. Ellingsen, M. L. von Bibra, P. M. McCulloch +3
We report the results of the first complete survey of an area of the Galactic Plane for maser emission from the 6.7-GHz transition of methanol. The survey covers a 10.6-square-degr…
Continuum emission associated with 6.7-GHz methanol masers
S. P. Ellingsen, R. P. Norris, P. M. McCulloch
We have used the Australia Telescope Compact Array (ATCA) to search for continuum emission toward three strong 6.7-GHz methanol maser sources. For two of the sources, G339.88-1.26…
