Single-Pulse Correlations in PSR B0329+54: Implications for Radio Emission Zones
Shyam S. Sharma, Tetsuya Hashimoto, Tomotsugu Goto +3
Individual radio pulses from a pulsar are directly linked to the underlying emission processes and the associated magnetic field geometry within its magnetosphere. Thus, single-pul…
Discovery and follow-up of a quasiperiodically nulling and sub-pulse drifting pulsar with the Murchison Widefield Array
G. Grover, N. D. R. Bhat, S. McSweeney +4
The phenomenon of pulsar nulling, where pulsars temporarily and stochastically cease their radio emission, is thought to be indicative of a `dying' pulsar, where radio emission cea…
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…
Independent discovery of a nulling pulsar with unusual sub-pulse drifting properties with the Murchison Widefield Array
Samuel J. McSweeney, N. D. Ramesh Bhat, Nicholas A. Swainston +10
We report the independent discovery of PSR J0027-1956 with the Murchison Widefield Array (MWA) in the ongoing Southern-sky MWA Rapid Two-meter (SMART) pulsar survey. J0027-1956 has…
Detection of frequency-dependent dispersion measure toward the millisecond pulsar PSR J2241-5236 from contemporaneous wide-band observations
Dilpreet Kaur, N. D. Ramesh Bhat, Shi Dai +4
Making precise measurements of pulsar dispersion measures (DMs) and applying suitable corrections for them is amongst the major challenges in high-precision timing programmes such…
Multiband Detection of Repeating FRB 20180916B
Ketan R. Sand, Jakob Faber, Vishal Gajjar +19
We present a multiband study of FRB 20180916B, a repeating source with a 16.3 day periodicity. We report the detection of 4, 1 and 7 bursts from observations spanning 3 days using…
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)…
Study of eclipses for Redback pulsar J12274853
Sanjay Kudale, Jayanta Roy, Bhaswati Bhattacharyya +2
We present a multi-frequency study of eclipse properties of a transitional redback millisecond pulsar J12274853 discovered in 2014 with the GMRT. Emission from this pulsar is ec…
The frequency-dependent behaviour of subpulse drifting: I. Carousel geometry and emission heights of PSR B0031-07
S. J. McSweeney, N. D. R. Bhat, G. Wright +2
The carousel model of pulsar emission attributes the phenomenon of subpulse drifting to a set of discrete sparks located very near the stellar surface rotating around the magnetic…
Detection of fast transients with radio interferometric arrays
N. D. R. Bhat, J. N. Chengalur, P. J. Cox +7
Next-generation radio arrays, including the Square Kilometre Array (SKA) and its pathfinders, will open up new avenues for exciting transient science at radio wavelengths. Their in…
