High Angular Resolution Radio Astronomy with the LBA and AuScope

The aim of this project is to use the technique of Very Long Baseline Interferometry (VLBI) to provide some of the highest angular resolution observations in astronomy and to use the same technique to provide fundamental parameters used to determine the International Terrestrial Reference Frame.

We will process data from the Long Baseline Array (which focuses primarily on astronomical research) and the AuScope array (which focuses primarily on geodetic research) to achieve these dual goals. The two approaches are complementary as the correlation of the data, which we propose to process on Magnus, is essentially the same, and the efficacy of each method is improved by the results of the other – astronomers need accurate telescope positions from geodesy to calibrate their data, and geodesists need the astronomical source structure to calibrate theirs.
