Long Baseline Array observing
The last few days have seen the ATNF telescopes combining with those of partner institutions to undertake observations using the technique of Very Long Baseline Interferometry (VLBI). The Parkes 64m telescope has an angular resolution measured in arcminutes (comparable to the human eye), the 6km baselines of the ATCA yield angular resolutions measured in arcseconds, and VLBI arrays with baselines of thousands of kilometers have angular resolutions of milli-arcseconds, which corresponds to linear resolutions of some astronomical units (Earth-Sun distances) within our Galaxy, or light-year scales in other galaxies. The ATNF telescopes work together with those from the UNiversity of Tasmania, the Hartebeesthoek Radio Astronomy Observatory in South Africa, and the Auckland University of Technology.
