A commensal Fast Radio Burst search pipeline for the Murchison Widefield Array
M. Sokolowski, I. S. Morrison, D. Price +9
We present a demonstration version of a commensal pipeline for Fast Radio Burst (FRB) searches using a real-time incoherent beam from the Murchison Widefield Array (MWA). The main…
The Southern-sky MWA Rapid Two-metre (SMART) pulsar survey -- II. Survey status, pulsar census, and first pulsar discoveries
N. D. R. Bhat, N. A. Swainston, S. J. McSweeney +19
In Paper I, we presented an overview of the Southern-sky MWA Rapid Two-metre (SMART) survey, including the survey design and search pipeline. While the combination of MWA's large f…
The Southern-sky MWA Rapid Two-metre (SMART) pulsar survey -- I. Survey design and processing pipeline
N. D. R. Bhat, N. A. Swainston, S. J. McSweeney +19
We present an overview of the Southern-sky MWA Rapid Two-metre (SMART) pulsar survey that exploits the MWA's large field of view and voltage capture system to survey the sky south…
A targeted search for repeating fast radio bursts with the MWA
J. Tian, G. E. Anderson, P. J. Hancock +7
We present a targeted search for low-frequency (144--215\,MHz) FRB emission from five repeating FRBs using 23.3\,hr of archival data taken with the Murchison Widefield Array (MWA)…
Spectral analysis of 22 radio pulsars using SKA-Low precursor stations
C. P. Lee, N. D. R. Bhat, M. Sokolowski +4
We present the first observational study of pulsars performed with the second-generation precursor stations to the low-frequency component of the Square Kilometre Array (SKA-Low):…
System equivalent flux density of Stokes I, Q, U, V of a polarimetric interferometer
A. T. Sutinjo, D. C. X. Ung, M. Sokolowski
We present the system equivalent flux density (SEFD) expressions for all four Stokes parameters: I, Q, U, V. The expressions were derived based on our derivation of SEFD I (for Sto…
High time resolution search for prompt radio emission from the long GRB 210419A with the Murchison Widefield Array
J. Tian, G. E. Anderson, P. J. Hancock +15
We present a low-frequency (170\textendash200\,MHz) search for prompt radio emission associated with the long GRB 210419A using the rapid-response mode of the Murchison Widefield A…
What is the SKA-Low Sensitivity for Your Favourite Radio Source ?
M. Sokolowski, S. J. Tingay, D. B. Davidson +8
The SKA will be the largest radio astronomy observatory ever built, providing unprecedented sensitivity over a very broad frequency (50 MHz to 15.3 GHz). The SKA-Low (50 - 350 MHz)…
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…
Early-time Searches for Coherent Radio Emission from Short GRBs with the Murchison Widefield Array
J. Tian, G. E. Anderson, P. J. Hancock +13
Here we present a low frequency (170-200MHz) search for coherent radio emission associated with nine short GRBs detected by the Swift and/or Fermi satellites using the Murchison Wi…
A broadband radio view of transient jet ejecta in the black hole candidate X-ray binary MAXI J1535-571
J. Chauhan, J. C. A. Miller-Jones, G. E. Anderson +19
We present a broadband radio study of the transient jets ejected from the black hole candidate X-ray binary MAXI J1535-571, which underwent a prolonged outburst beginning on 2 Sept…
V473 Lyr, a modulated, period-doubled Cepheid, and U TrA, a double-mode Cepheid observed by MOST
L. Molnár, A. Derekas, R. Szabó +36
Space-based photometric measurements first revealed low-amplitude irregularities in the pulsations of Cepheid stars, but their origins and how commonly they occur remain uncertain.…
