The angular resolution of a telescope improves with the diameter of
the dish, or with the spacing between elements of the array. The
technique of Very Long Baseline Interferometry uses antennas spaced
hundreds to thousands of kilometres apart to achieve angular resolutions measured
in milli-arcseconds. The ATNF telescopes work together with those from
the University of Tasmania, the South
African Radio Astronomy Observatory, and SpaceOps New Zealand
to form the Long Baseline Array. A five-day LBA session is
currently underway, with projects scheduled being
"Physics of Gamma Ray Emitting Active Galactic Nuclei",
"Pinpointing an ultra-long period magnetar",
"Probing Gaia parallax zero-points at low Galactic latitudes using VLBI astrometry of radio stars",
"The EMU-VLBI pilot survey - uncovering milliarcsecond radio structures in the Southern sky",
"Zooming in on a white dwarf around a reignited star", and
"Parsec-scale structure of radio sources showing HI-21cm absorption".
Data is correlated using the DiFX software correlator at the
Pawsey Supercomputing Research Centre in Perth.
