The Murchison Widefield Array Transients Survey (MWATS). A search for low frequency variability in a bright Southern hemisphere sample
M. E. Bell, Tara Murphy, P. J. Hancock +38
We report on a search for low-frequency radio variability in 944 bright (> 4Jy at 154 MHz) unresolved, extragalactic radio sources monitored monthly for several years with the Murc…
GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey I: A low-frequency extragalactic catalogue
Natasha Hurley-Walker, Joseph R. Callingham, Paul J. Hancock +40
Using the Murchison Widefield Array (MWA), the low-frequency Square Kilometre Array (SKA1 LOW) precursor located in Western Australia, we have completed the GaLactic and Extragalac…
Broadband Spectral Modeling of the Extreme Gigahertz-Peaked Spectrum Radio Source PKS B0008-421
J. R. Callingham, B. M. Gaensler, R. D. Ekers +40
We present broadband observations and spectral modeling of PKS B0008-421, and identify it as an extreme gigahertz-peaked spectrum (GPS) source. PKS B0008-421 is characterized by th…
Ionospheric modelling using GPS to calibrate the MWA. 1: Comparison of first order ionospheric effects between GPS models and MWA observations
B. S. Arora, J. Morgan, S. M. Ord +56
We compare first order (refractive) ionospheric effects seen by the Murchison Widefield Array (MWA) with the ionosphere as inferred from Global Positioning System (GPS) data. The f…
GLEAM: The GaLactic and Extragalactic All-sky MWA survey
R. B. Wayth, E. Lenc, M. E. Bell +52
GLEAM, the GaLactic and Extragalactic All-sky MWA survey, is a survey of the entire radio sky south of declination +25 deg at frequencies between 72 and 231 MHz, made with the Murc…
The Murchison Widefield Array Correlator
S. M. Ord, B. Crosse, D. Emrich +64
The Murchison Widefield Array (MWA) is a Square Kilometre Array (SKA) Precursor. The telescope is located at the Murchison Radio--astronomy Observatory (MRO) in Western Australia (…
The High Time and Frequency Resolution Capabilities of the Murchison Widefield Array
S. E. Tremblay, S. M. Ord, N. D. R. Bhat +37
The science cases for incorporating high time resolution capabilities into modern radio telescopes are as numerous as they are compelling. Science targets range from exotic sources…
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…
On the detection and tracking of space debris using the Murchison Widefield Array. I. Simulations and test observations demonstrate feasibility
S. J. Tingay, D. L. Kaplan, B. McKinley +60
The Murchison Widefield Array (MWA) is a new low frequency interferomeric radio telescope. The MWA is the low frequency precursor to the Square Kilometre Array (SKA) and is the fir…
A 189 MHz, 2400 square degree polarization survey with the Murchison Widefield Array 32-element prototype
