Abstract The Murchison Widefield Array (MWA) is a next-generation radio telescope currently under construction in the remote Western Australia(More)
Spread over an area in Western Australia, this telescope is being designed to study the sun and its inner heliosphere, and time-varying astronomical phenomena. ABSTRACT | The Murchison Widefield Array is a dipole-based aperture array synthesis telescope designed to operate in the 80–300 MHz frequency range. It is capable of a wide range of science(More)
— The interferometric technique known as peeling addresses many of the challenges faced when observing with low-frequency radio arrays, and is a promising tool for the associated calibration systems. We investigate a real-time peeling implementation for next-generation radio interferometers such as the Murchison Widefield Array (MWA). The MWA is being built(More)

We present the first spectroscopic images of solar radio transients from the prototype for the Murchison Widefield Array, observed on 2010 March 27. Our observations span the instantaneous frequency band 170.9– 201.6 MHz. Though our observing period is characterized as a period of " low " to " medium " activity, one broadband emission feature and numerous(More)
A new generation of observational science instruments is dramatically increasing collected data volumes in a range of fields. These instruments include the Square Kilometre Array (SKA), Large Synoptic Survey Telescope (LSST), terrestrial sensor networks, and NASA satellites participating in " decadal survey " missions. Their unprecedented coverage and(More)
We present the first results from the V-FASTR experiment, a commensal search for fast transient radio bursts using the Very Long Baseline Array (VLBA). V-FASTR is unique in that the widely spaced VLBA antennas provide a discriminant against non-astronomical signals and a mechanism for the localization and identification of events that is not possible with(More)
