Digital Instrumentation for the Radio Astronomy Community
Aaron Parsons, Dan Werthimer, Donald Backer +21
Time-to-science is an important figure of merit for digital instrumentation serving the astronomical community. A digital signal processing (DSP) community is forming that uses sha…
Precision VLBI astrometry: Instrumentation, algorithms and pulsar parallax determination
A. T. Deller
(Abridged) This thesis describes the development of DiFX, the first general-purpose software correlator for radio interferometry, and its use with the Australian Long Baseline Arra…
Science with ASKAP - the Australian Square Kilometre Array Pathfinder
S. Johnston, R. Taylor, M. Bailes +47
[ABRIDGED VERSION] The future of cm and m-wave astronomy lies with the Square Kilometre Array (SKA), a telescope under development by a consortium of 17 countries. The SKA will be…
The use of the Long Baseline Array in Australia for precise geodesy and absolute astrometry
Leonid Petrov, Chris Phillips, Alessandra Bertarini +3
We report the results of a successful 12 hour 22 GHz VLBI experiment using a heterogeneous network that includes radio telescopes of the Long Baseline Array (LBA) in Australia and…
Extremely high precision VLBI astrometry of PSR J0437-4715 and implications for theories of gravity
A. T. Deller, J. P. W. Verbiest, S. J. Tingay +1
Using the recently upgraded Long Baseline Array, we have measured the trigonometric parallax of PSR J0437-4715 to better than 1% precision, the most precise pulsar distance determi…
VLBI detection of an Infrared-Faint Radio Source
Ray P. Norris, Steven Tingay, Chris Phillips +3
Infrared-Faint Radio Sources represent a new and unexpected class of object which is bright at radio wavelengths but unusually faint at infrared wavelengths. If, like most mJy radi…
