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…
