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…
Pulsar B1237+25 Aberration/Retardation Analysis from Decimeter to Decameter Wavelength: Challenge to "Radius-to-Frequency Mapping"
Joanna M. Rankin, Vyacheslav Zakharenko, Oleg Ulyanov +9
PSR B1237+25 is perhaps the canonical example of a pulsar with a core/double cone profile. Moreover, it is bright with little spectral turnover, and its profile perhaps uniquely re…
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…
