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…
Limits on low frequency radio emission from southern exoplanets with the Murchison Widefield Array
Tara Murphy, Martin E. Bell, David L. Kaplan +39
We present the results of a survey for low frequency radio emission from 17 known exoplanetary systems with the Murchison Widefield Array. This sample includes 13 systems that have…
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…
Inter-relationship between the Two Emission Cones of B1237+25
Yogesh Maan, Avinash A. Deshpande
The origin of two distinct pairs of conal emission components in pulsars, associated with the "outer" and the "inner" emission cones, as well as the marked difference in their obse…
Study of Redshifted HI from the Epoch of Reionization with Drift scan
Sourabh Paul, Shiv K. Sethi, Ravi Subrahmanyan +37
The detection of the Epoch of Reionization (EoR) in the redshifted 21-cm line is a challenging task. Here we formulate the detection of the EoR signal using the drift scan strategy…
WSClean: an implementation of a fast, generic wide-field imager for radio astronomy
A. R. Offringa, B. McKinley, N. Hurley-Walker +50
Astronomical widefield imaging of interferometric radio data is computationally expensive, especially for the large data volumes created by modern non-coplanar many-element arrays.…
