First results from the ATCA 18 GHz pilot survey
R. Ricci, E. M. Sadler, R. D. Ekers +7
As a pilot study for the first all-sky radio survey at short wavelengths, we have observed 1216 sq. deg. of the southern sky at 18GHz (16mm) using a novel wide-band (3.4GHz bandwid…
Contaminants in ATCA baselines with shadowing: a case study of cross talk in short-spacing interferometers
Ravi Subrahmanyan, Avinash A. Deshpande
Interferometric telescopes made of close-packed antenna elements are an important tool for imaging extended radio sources, specifically structures that have angular sizes comparabl…
Modulations in the radio light curve of the Type IIb Supernova 2001ig: Evidence for a Wolf-Rayet binary progenitor?
Stuart D. Ryder, Elaine M. Sadler, Ravi Subrahmanyan +3
We describe the radio evolution of SN 2001ig in NGC 7424, from 700 days of multi-frequency monitoring with the Australia Telescope Compact Array (ATCA) and the Very Large Array (VL…
