A search for Fast Radio Bursts at low frequencies with Murchison Widefield Array high time resolution imaging
S. J. Tingay, C. M. Trott, R. B. Wayth +26
We present the results of a pilot study search for Fast Radio Bursts (FRBs) using the Murchison Widefield Array (MWA) at low frequencies (139 - 170 MHz). We utilised MWA data obtai…
The Effect of Interplanetary Scintillation on Epoch of Reionisation Power Spectra
Cathryn M. Trott, Steven J. Tingay
Interplanetary Scintillation (IPS) induces intensity fluctuations in small angular size astronomical radio sources via the distortive effects of spatially and temporally varying el…
Murchison Widefield Array Observations of Anomalous Variability: A Serendipitous Night-time Detection of Interplanetary Scintillation
D. L. Kaplan, S. J. Tingay, P. K. Manoharan +33
We present observations of high-amplitude rapid (2 s) variability toward two bright, compact extragalactic radio sources out of several hundred of the brightest radio sources in on…
Confirmation of Wide-Field Signatures in Redshifted 21 cm Power Spectra
Nithyanandan Thyagarajan, Daniel C. Jacobs, Judd D. Bowman +52
We confirm our recent prediction of the "pitchfork" foreground signature in power spectra of high-redshift 21 cm measurements where the interferometer is sensitive to large-scale s…
The Cosmic Dawn and Epoch of Reionization with the Square Kilometre Array
L. V. E. Koopmans, J. Pritchard, G. Mellema +42
Concerted effort is currently ongoing to open up the Epoch of Reionization (EoR) (15-6) for studies with IR and radio telescopes. Whereas IR detections have been made of sou…
Real-time imaging of density ducts between the plasmasphere and ionosphere
Shyeh Tjing Loi, Tara Murphy, Iver H. Cairns +38
Ionization of the Earth's atmosphere by sunlight forms a complex, multi-layered plasma environment within the Earth's magnetosphere, the innermost layers being the ionosphere and p…
A search for variable and transient radio sources in the extended Chandra Deep Field South at 5.5 GHz
M. E. Bell, M. T. Huynh, P. Hancock +5
We present a three epoch survey for transient and variables in the extended Chandra Deep Field South at 5.5 GHz with the Australia Telescope Compact Array. A region covering …
Foregrounds in Wide-Field Redshifted 21 cm Power Spectra
Nithyanandan Thyagarajan, Daniel C. Jacobs, Judd D. Bowman +61
Detection of 21~cm emission of HI from the epoch of reionization, at redshifts z>6, is limited primarily by foreground emission. We investigate the signatures of wide-field measure…
Fast Transients at Cosmological Distances with the SKA
J. -P. Macquart, E. Keane, K. Grainge +14
Impulsive radio bursts that are detectable across cosmological distances constitute extremely powerful probes of the ionized Inter-Galactic Medium (IGM), intergalactic magnetic fie…
The low-frequency environment of the Murchison Widefield Array: radio-frequency interference analysis and mitigation
A. R. Offringa, R. B. Wayth, N. Hurley-Walker +62
The Murchison Widefield Array (MWA) is a new low-frequency interferometric radio telescope built in Western Australia at one of the locations of the future Square Kilometre Array (…
