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…
Event-horizon-scale structure in the supermassive black hole candidate at the Galactic Centre
Sheperd Doeleman, Jonathan Weintroub, Alan E. E. Rogers +25
The cores of most galaxies are thought to harbour supermassive black holes, which power galactic nuclei by converting the gravitational energy of accreting matter into radiation (r…
The low-frequency characteristics of PSR J0437-4715 observed with the Murchison Widefield Array
N. D. Ramesh Bhat, S. M. Ord, S. E. Tremblay +37
We report on the detection of the millisecond pulsar PSR J0437-4715 with the Murchison Widefield Array (MWA) at a frequency of 192 MHz. Our observations show rapid modulations of p…
The Murchison Widefield Array Commissioning Survey: A Low-Frequency Catalogue of 14,110 Compact Radio Sources over 6,100 Square Degrees
Natasha Hurley-Walker, John Morgan, Randall B. Wayth +49
We present the results of an approximately 6,100 square degree 104--196MHz radio sky survey performed with the Murchison Widefield Array during instrument commissioning between 201…
