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…
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…
Simultaneous Observations of Giant Pulses from the Crab Pulsar, with the Murchison Widefield Array and Parkes Radio Telescope: Implications for the Giant Pulse Emission Mechanism
S. I. Oronsaye, S. M. Ord, N. D. R. Bhat +28
We report on observations of giant pulses from the Crab pulsar performed simultaneously with the Parkes radio telescope and the incoherent combination of the Murchison Widefield Ar…
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…
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…
An analysis of the halo and relic radio emission from Abell 3376 from Murchison Widefield Array observations
Lijo T. George, K. S. Dwarakanath, M. Johnston-Hollitt +48
We have carried out multiwavelength observations of the near-by () rich, merging galaxy cluster Abell 3376 with the Murchison Widefield Array (MWA). As a part of the GaLac…
