First Season MWA Phase II EoR Power Spectrum Results at Redshift 7
W. Li, J. C. Pober, N. Barry +44
The compact configuration of Phase II of the Murchison Widefield Array (MWA) consists of both a redundant subarray and pseudo-random baselines, offering unique opportunities to per…
Science with the Murchison Widefield Array: Phase I Results and Phase II Opportunities
A. P. Beardsley, M. Johnston-Hollitt, C. M. Trott +56
The Murchison Widefield Array (MWA) is an open access telescope dedicated to studying the low frequency (80300 MHz) southern sky. Since beginning operations in mid 2013, the MWA…
A VOEvent based automatic trigger system for the Murchison Widefield Array
P. J. Hancock, G. E. Anderson, A. Williams +22
The Murchison Widefield Array (MWA) is an electronically steered low frequency (\,MHz) radio interferometer, with a `slew' time less than 8seconds. Low frequency (\…
A high time resolution study of the millisecond pulsar J2241-5236 at frequencies below 300 MHz
D. Kaur, N. D. R. Bhat, S. E. Tremblay +20
One of the major challenges for pulsar timing array (PTA) experiments is the mitigation of the effects of the turbulent interstellar medium (ISM) from timing data. These can potent…
Gridded and direct Epoch of Reionisation bispectrum estimates using the Murchison Widefield Array
Cathryn M. Trott, Catherine A. Watkinson, Christopher H. Jordan +42
We apply two methods to estimate the 21~cm bispectrum from data taken within the Epoch of Reionisation (EoR) project of the Murchison Widefield Array (MWA). Using data acquired wit…
Hunting for radio emission from the intermittent pulsar J1107-5907 at low frequencies
B. W. Meyers, S. E. Tremblay, N. D. R. Bhat +30
The rare intermittent pulsars pose some of the most challenging questions surrounding the pulsar emission mechanism, but typically have relatively minimal low-frequency (…
No low-frequency emission from extremely bright Fast Radio Bursts
M. Sokolowski, N. D. R. Bhat, J. P. Macquart +23
We present the results of a coordinated campaign conducted with the Murchison Widefield Array (MWA) to shadow Fast Radio Bursts (FRBs) detected by the Australian Square Kilometre A…
The Phase II Murchison Widefield Array: Design Overview
Randall B. Wayth, Steven J. Tingay, Cathryn M. Trott +26
We describe the motivation and design details of the "Phase II" upgrade of the Murchison Widefield Array (MWA) radio telescope. The expansion doubles to 256 the number of antenna t…
In situ measurement of MWA primary beam variation using ORBCOMM
J. L. B. Line, B. McKinley, J. Rasti +21
We provide the first in situ measurements of antenna element (tile) beam shapes of the Murchison Widefield Array (MWA), a low radio-frequency interferometer and an SKA precursor. M…
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…
Comparing Redundant and Sky Model Based Interferometric Calibration: A First Look with Phase II of the MWA
W. Li, J. C. Pober, B. J. Hazelton +53
Interferometric arrays seeking to measure the 21 cm signal from the Epoch of Reionization must contend with overwhelmingly bright emission from foreground sources. Accurate recover…
Limits on radio emission from meteors using the MWA
Xiang Zhang, Paul Hancock, Hadrien A. R. Devillepoix +20
Recently, low frequency, broadband radio emission has been observed accompanying bright meteors by the Long Wavelength Array (LWA). The broadband spectra between 20 and 60 MHz were…
A Serendipitous MWA Search for Narrow-band and Broad-band Low Frequency Radio Transmissions from 1I/2017 U1 'Oumuamua
S. J. Tingay, D. L. Kaplan, E. Lenc +18
We examine data from the Murchison Widefield Array (MWA) in the frequency range 72 -- 102 MHz for a field-of-view that serendipitously contained the interstellar object 'Oumuamua o…
Follow up of GW170817 and its electromagnetic counterpart by Australian-led observing programs
I. Andreoni, K. Ackley, J. Cooke +122
The discovery of the first electromagnetic counterpart to a gravitational wave signal has generated follow-up observations by over 50 facilities world-wide, ushering in the new era…
The Engineering Development Array: A low frequency radio telescope utilising SKA precursor technology
Randall Wayth, Marcin Sokolowski, Tom Booler +21
We describe the design and performance of the Engineering Development Array (EDA), which is a low frequency radio telescope comprising 256 dual-polarisation dipole antennas working…
