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 (…
Pre-selection of the Candidate Fields for Deep Imaging of the Epoch of Reionization with SKA1-Low
Qian Zheng, Xiang-Ping Wu, Quan Guo +4
The Square Kilometre Array (SKA) will be the first low-frequency instrument with the capability to directly image the structures of the Epoch of Reionization (EoR). Indeed, deep im…
The Murchison Widefield Array Transients Survey (MWATS). A search for low frequency variability in a bright Southern hemisphere sample
M. E. Bell, Tara Murphy, P. J. Hancock +38
We report on a search for low-frequency radio variability in 944 bright (> 4Jy at 154 MHz) unresolved, extragalactic radio sources monitored monthly for several years with the Murc…
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…
