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…
Pulsar searches of Fermi-LAT gamma-ray sources with the MWA
C. P. Lee, N. D. R. Bhat, B. W. Meyers +2
Searches of unassociated gamma-ray sources in the Fermi-LAT catalogues have led to the discoveries of around a fifth of all known millisecond pulsars (MSPs). These searches have al…
The ONs and OFFs of Pulsar Radio Emission: Characterizing the Nulling Phenomenon
Garvit Grover, N. D. Ramesh Bhat, Samuel J. McSweeney +4
Radio emission from pulsars is known to exhibit a diverse range of emission phenomena, among which nulling, where the emission becomes temporarily undetectable, is an intriguing on…
Improving pulsar search efficiency in next-generation pulsar surveys with artificial intelligence
Qiuyang Fu, Mengyao Xue, Weiwei Zhu +12
Pulsar searching with next-generation radio telescopes requires efficiently sifting through millions of candidates generated by search pipelines to identify the most promising ones…
Relevance of Murchison Widefield Array Interplanetary Scintillation Observations to Heliospheric Transient Catalogues
A. Waszewski, J. S. Morgan, M. C. M. Cheung +6
We have conducted a comprehensive comparison of interplanetary scintillation (IPS) observations taken by the Murchison Widefield Array (MWA) with several heliospheric transient eve…
Latitudinal dependence of the solar wind during periods of high and low activity through interplanetary scintillation
A. Waszewski, J. S. Morgan, R. Ekers +5
We present a study of the solar wind over different periods of the solar cycle, specifically focussing on the minimum between solar cycles 24 and 25, and the active, ascending phas…
Probing magneto-ionic microstructure towards the Vela pulsar using a prototype SKA-Low station
C. P. Lee, N. D. R. Bhat, M. Sokolowski +2
The Vela pulsar (J0835-4510) is known to exhibit variations in Faraday rotation and dispersion on multi-decade timescales due to the changing sightline through the surrounding Vela…
The CRAFT Coherent (CRACO) upgrade I: System Description and Results of the 110-ms Radio Transient Pilot Survey
Z. Wang, K. W. Bannister, V. Gupta +40
We present the first results from a new backend on the Australian Square Kilometre Array Pathfinder, the Commensal Realtime ASKAP Fast Transient COherent (CRACO) upgrade. CRACO rec…
Imaging pulsar census of the Galactic Plane using MWA VCS data
S. Sett, M. Sokolowski, E. Lenc +1
Traditional pulsar surveys have primarily employed time-domain periodicity searches. However, these methods are susceptible to effects like scattering, eclipses and orbital motion.…
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…
Resolving moving heliospheric structures using interplanetary scintillation observations with the Murchison Widefield Array
A. Waszewski, J. S. Morgan, R. Chhetri +4
We have conducted a blind search in 49 consecutive days of interplanetary scintillation observations made by the Murchison Widefield Array from mid-2019, with overlapping daily obs…
Image-based searches for pulsar candidates using MWA VCS data
S. Sett, N. D. R. Bhat, M. Sokolowski +1
Pulsars have proven instrumental in exploring a wide variety of physics. Pulsars at low radio frequencies is crucial to further our understanding of spectral properties and emissio…
