The Engineering Development Array: A low frequency radio telescope utilising SKA precursor technology
Randall Wayth, Marcin Sokolowski, Tom Booler +21
We describe the design and performance of the Engineering Development Array (EDA), which is a low frequency radio telescope comprising 256 dual-polarisation dipole antennas working…
A Digital-Receiver for the Murchison Widefield Array
Thiagaraj Prabu, K. S. Srivani, D. Anish Roshi +55
An FPGA-based digital-receiver has been developed for a low-frequency imaging radio interferometer, the Murchison Widefield Array (MWA). The MWA, located at the Murchison Radio-ast…
The Engineering Development Array 2: design, performance and lessons from an SKA-Low prototype station
Randall Wayth, Marcin Sokolowski, Jess Broderick +21
We present the Engineering Development Array 2, which is one of two instruments built as a second generation prototype station for the future Square Kilometre Array Low Frequency A…
Serendipitous discovery of a dying Giant Radio Galaxy associated with NGC 1534, using the Murchison Widefield Array
Natasha Hurley-Walker, Melanie Johnston-Hollitt, Ron Ekers +41
Recent observations with the Murchison Widefield Array at 185~MHz have serendipitously unveiled a heretofore unknown giant and relatively nearby () radio galaxy associa…
Fast Holographic Deconvolution: a new technique for precision radio interferometry
Ian Sullivan, Miguel Morales, Bryna Hazelton +48
We introduce the Fast Holographic Deconvolution method for analyzing interferometric radio data. Our new method is an extension of A-projection/software-holography/forward modeling…
Science with the Murchison Widefield Array
Judd D. Bowman, Iver Cairns, David L. Kaplan +58
Significant new opportunities for astrophysics and cosmology have been identified at low radio frequencies. The Murchison Widefield Array is the first telescope in the Southern Hem…
