Opportunity Lost in Searching for Technosignatures
Steve Prabu, David DeBoer, Andrew Siemion +6
The sensitivity of radio technosignature searches has improved dramatically over the last five decades; however, as the RFI environment from which these searches are conducted has…
A fast radio burst from a non-targeted low-frequency survey
Cristian Di Pietrantonio, Marcin Sokolowski, Clancy W. James +13
Fast radio bursts (FRBs) are bright, millisecond-duration transient radio signals of extragalactic origin with unknown source and emission mechanisms. While several thousand FRBs h…
The Southern-sky MWA Rapid Two-metre (SMART) pulsar survey--IV. Survey update and an atlas of 205 non-recycled southern pulsars
N. D. R. Bhat, C. P. Lee, S. J. McSweeney +13
The SMART survey is an ambitious effort to conduct sensitive searches for pulsars and fast transients at 140-170 MHz. The novelty of voltage recording, long dwell times and the hig…
The Murchison Widefield Array Phase III upgrade: Sensitivity Doubled, Number of Baselines Quadrupled, Flexibility Enhanced, and EoR Observations Optimised
S. J. Tingay, M. Johnston-Hollitt, R. B. Wayth +32
We describe the latest iteration of upgrades (designated Phase III) to the Murchison Widefield Array (MWA), in the fourth paper in a series that covers the evolution of the telesco…
The Southern-sky MWA Rapid Two-metre (SMART) pulsar survey -- III. A census of millisecond pulsars at 154 MHz
C. P. Lee, N. D. R. Bhat, B. W. Meyers +9
Observations of millisecond pulsars (MSPs) at low radio frequencies play an important role in understanding the Galactic pulsar population and characterising both their emission pr…
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…
MWA rapid follow-up of gravitational wave transients: prospects for detecting prompt radio counterparts
J. Tian, G. E. Anderson, A. J. Cooper +17
We present and evaluate the prospects for detecting coherent radio counterparts to gravitational wave (GW) events using Murchison Widefield Array (MWA) triggered observations. The…
MWAX: A New Correlator for the Murchison Widefield Array
I. S. Morrison, B. Crosse, G. Sleap +7
We describe the design, validation, and commissioning of a new correlator termed "MWAX" for the Murchison Widefield Array (MWA) low-frequency radio telescope. MWAX replaces an earl…
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…
Discovery of a steep-spectrum low-luminosity pulsar with the Murchison Widefield Array
N. A. Swainston, N. D. R. Bhat, M. Sokolowski +17
We report the discovery of the first new pulsar with the Murchison Widefield Array (MWA), PSR J00361033, a long-period (0.9 s) nonrecycled pulsar with a dispersion measure (DM)…
A Southern-Hemisphere all-sky radio transient monitor for SKA-Low prototype stations
M. Sokolowski, R. B. Wayth, N. D. R. Bhat +20
We present the first southern-hemisphere all-sky imager and radio-transient monitoring system implemented on two prototype stations of the low-frequency component of the Square Kil…
Calibration database for the Murchison Widefield Array All-Sky Virtual Observatory
M. Sokolowski, C. H. Jordan, G. Sleap +11
We present a calibration component for the Murchison Widefield Array All-Sky Virtual Observatory (MWA ASVO) utilising a newly developed PostgreSQL database of calibration solutions…
Deep multi-redshift limits on Epoch of Reionisation 21cm Power Spectra from Four Seasons of Murchison Widefield Array Observations
Cathryn M. Trott, C. H. Jordan, S. Midgley +33
We compute the spherically-averaged power spectrum from four seasons of data obtained for the Epoch of Reionisation (EoR) project observed with the Murchison Widefield Array (MWA).…
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…
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…
