The MWA Interestingly Deep AStrophysical (MIDAS) Survey: Survey Description and First Data Release
S. Paterson, N. Seymour, N. Hurley-Walker +4
We present the deepest MWA survey to date, targeting the GAMA9 and GAMA23 survey fields at 215.68 MHz. With a bandwidth of 30.72 MHz, the two images cover …
GaLactic and Extragalactic All-sky Murchison Widefield Array eXtended (GLEAM-X) survey II: Second Data Release
K. Ross, N. Hurley-Walker, T. J. Galvin +9
We present the second data release for the GaLactic and Extragalactic All-sky Murchison Widefield Array eXtended (GLEAM-X) survey. This data release is an area of 12,892-deg^2 arou…
Spectral Variability of Radio Sources at Low Frequencies
K. Ross, J. R. Callingham, N. Hurley-Walker +7
Spectral variability of radio sources encodes information about the conditions of intervening media, source structure, and emission processes. With new low-frequency radio interfer…
The challenges of low-frequency radio polarimetry: lessons from the Murchison Widefield Array
Emil Lenc, C. S. Anderson, N. Barry +26
We present techniques developed to calibrate and correct Murchison Widefield Array (MWA) low frequency (72-300 MHz) radio observations for polarimetry. The extremely wide field-of-…
Characterisation of the ionosphere above the Murchison Radio Observatory using the Murchison Widefield Array
C. H. Jordan, S. Murray, C. M. Trott +6
We detail new techniques for analysing ionospheric activity, using Epoch of Reionisation (EoR) datasets obtained with the Murchison Widefield Array (MWA), calibrated by the `Real-T…
A search for long-timescale, low-frequency radio transients
Tara Murphy, David L. Kaplan, Steve Croft +30
We present a search for transient and highly variable sources at low radio frequencies (150-200 MHz) that explores long timescales of 1-3 years. We conducted this search by compari…
Galactic synchrotron emissivity measurements between 250° < l < 355° from the GLEAM survey with the MWA
H. Su, N. Hurley-Walker, C. A. Jackson +20
Synchrotron emission pervades the Galactic plane at low radio frequencies, originating from cosmic ray electrons interacting with the Galactic magnetic field. Using a low-frequency…
Ionospheric Modelling using GPS to Calibrate the MWA. II: Regional ionospheric modelling using GPS and GLONASS to estimate ionospheric gradients
B. S. Arora, J. Morgan, S. M. Ord +18
We estimate spatial gradients in the ionosphere using the Global Positioning System (GPS) and GLONASS (Russian global navigation system) observations, utilising data from multiple…
Low Radio Frequency Observations and Spectral Modelling of the Remnant of Supernova 1987A
J. R. Callingham, B. M. Gaensler, G. Zanardo +17
We present Murchison Widefield Array observations of the supernova remnant (SNR) 1987A between 72 and 230 MHz, representing the lowest frequency observations of the source to date.…
Limits of noise and confusion in the MWA GLEAM year 1 survey
T. M. O. Franzen, C. A. Jackson, J. R. Callingham +21
The GaLactic and Extragalactic All-sky MWA survey (GLEAM) is a new relatively low resolution, contiguous 72-231 MHz survey of the entire sky south of declination +25 deg. In this p…
The MWA GLEAM 4Jy Sample; a new large, bright radio source sample at 151 MHz
C A Jackson, T M O Franzen, N Seymour +25
This paper outlines how the new GaLactic and Extragalactic All-sky MWA Survey (GLEAM, Wayth et al. 2015), observed by the Murchison Widefield Array covering the frequency range 72…
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…
