Real-time triggering capabilities for Fast Radio Bursts at the MeerKAT telescope
F. Jankowski, M. Berezina, B. W. Stappers +9
Fast Radio Bursts (FRBs) are bright enigmatic radio pulses of roughly millisecond duration that come from extragalactic distances. As part of the MeerTRAP project, we use the MeerK…
The Thousand-Pulsar-Array programme on MeerKAT II: observing strategy for pulsar monitoring with subarrays
X. Song, P. Weltevrede, M. J. Keith +15
The Thousand Pulsar Array (TPA) project currently monitors about 500 pulsars with the sensitive MeerKAT radio telescope by using subarrays to observe multiple sources simultaneousl…
Revisiting profile instability of J1022+1001
Prajwal V. Padmanabh, Ewan D. Barr, David J. Champion +4
Millisecond pulsars in timing arrays can act as probes for gravitational wave detection and improving the solar system ephemerides among several other applications. However, the st…
Pulsar Candidate Identification Using Semi-Supervised Generative Adversarial Networks
Vishnu Balakrishnan, David Champion, Ewan Barr +3
Machine learning methods are increasingly helping astronomers identify new radio pulsars. However, they require a large amount of labelled data, which is time consuming to produce…
The Thousand-Pulsar-Array programme on MeerKAT IV: Polarisation properties of young, energetic pulsars
M. Serylak, S. Johnston, M. Kramer +16
We present observations of 35 high spin-down energy radio pulsars using the MeerKAT telescope. Polarisation profiles and associated parameters are also presented. We derive the geo…
The SUrvey for Pulsars and Extragalactic Radio Bursts V: Recent Discoveries and Full Timing Solutions
R. Spiewak, C. Flynn, S. Johnston +10
The SUrvey for Pulsars and Extragalactic Radio Bursts ran from 2014 April to 2019 August, covering a large fraction of the southern hemisphere at mid- to high-galactic latitudes, a…
Simultaneous multi-telescope observations of FRB 121102
M. Caleb, B. W. Stappers, T. D. Abbott +29
We present 11 detections of FRB 121102 in ~3 hours of observations during its 'active' period on the 10th of September 2019. The detections were made using the newly deployed MeerT…
The MeerKAT Telescope as a Pulsar Facility: System verification and early science results from MeerTime
M. Bailes, A. Jameson, F. Abbate +72
We describe system verification tests and early science results from the pulsar processor (PTUSE) developed for the newly-commissioned 64-dish SARAO MeerKAT radio telescope in Sout…
Optimal periodicity searching: Revisiting the Fast Folding Algorithm for large-scale pulsar surveys
V. Morello, E. D. Barr, B. W. Stappers +2
The Fast Folding Algorithm (FFA) is a phase-coherent search technique for periodic signals. It has rarely been used in radio pulsar searches, having been historically supplanted by…
Constraints from globular cluster pulsars on the magnetic field in the Galactic halo
Federico Abbate, Andrea Possenti, Caterina Tiburzi +4
The Galactic magnetic field plays an important role in the evolution of the Galaxy, but its small-scale behaviour is still poorly known. It is also unknown whether it permeates the…
Shapiro delay in PSR~J18112405
C. Ng, L. Guillemot, P. C. C. Freire +5
This paper presents the first detection of Shapiro delay from the binary millisecond pulsar PSR J1811-2405. We report a 11- measurement of the orthometric amplitude, h=6.8(6…
The High Time Resolution Universe Pulsar Survey -- XVI. Discovery and timing of 40 pulsars from the southern Galactic plane
A. D. Cameron, D. J. Champion, M. Bailes +23
We present the results of processing an additional 44% of the High Time Resolution Universe South Low Latitude (HTRU-S LowLat) pulsar survey, the most sensitive blind pulsar survey…
