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…

Modelling of the Spectral Energy Distribution of Fornax A: Leptonic and Hadronic Production of High Energy Emission from the Radio Lobes

B. McKinley, R. Yang, M. López-Caniego +52

We present new low-frequency observations of the nearby radio galaxy Fornax A at 154 MHz with the Murchison Widefield Array, microwave flux-density measurements obtained from WMAP…

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 first Murchison Widefield Array low frequency radio observations of cluster scale non-thermal emission: the case of Abell 3667

L. Hindson, M. Johnston-Hollitt, N. Hurley-Walker +51

We present the first Murchison Widefield Array observations of the well-known cluster of galaxies Abell 3667 (A3667) between 105 and 241 MHz. A3667 is one of the best known example…

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…
