MWA Tied-Array Processing IV: A Multi-Pixel Beamformer for Pulsar Surveys and Ionospheric Corrected Localisation
N. A. Swainston, N. D. R. Bhat, I. S. Morrison +4
The Murchison Widefield Array (MWA) is a low-frequency aperture array capable of high-time and frequency resolution astronomy applications such as pulsar studies. The large field-o…
An Ultra-High Time Resolution Cosmic Ray Detection Mode for the Murchison Widefield Array
A. Williamson, C. W. James, S. J. Tingay +2
The radio-wavelength detection of extensive air showers (EAS) initiated by cosmic-ray interactions in the Earth's atmosphere is a promising technique for investigating the origin o…
MWA tied-array processing III: Microsecond time resolution via a polyphase synthesis filter
S. J. McSweeney, S. M. Ord, N. D. R. Bhat +5
A new high time resolution observing mode for the Murchison Widefield Array (MWA) is described, enabling full polarimetric observations with up to 30.72 MHz of bandwidth and a time…
MWA Tied-Array Processing I: Calibration and Beamformation
S. M. Ord, S. E. Tremblay, S. J. McSweeney +5
The Murchison Widefield Array is a low-frequency Square Kilometre Array precursor located at the Murchison Radio-astronomy Observatory in Western Australia. Primarily designed as a…
Observations of Low-Frequency Radio Emission from Millisecond Pulsars and Multipath Propagation in the Interstellar Medium
N. D. R. Bhat, S. E. Tremblay, F. Kirsten +23
Studying the gravitational-wave sky with pulsar timing arrays (PTAs) is a key science goal for the Square Kilometre Array (SKA) and its pathfinder telescopes. With current PTAs rea…
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-…
