The High Time Resolution Universe Pulsar Survey -- XVIII. The reprocessing of the HTRU-S Low Lat survey around the Galactic centre using a Fast Folding Algorithm pipeline for accelerated pulsars
J. Wongphechauxsorn, D. J. Champion, M. Bailes +18
The HTRU-S Low Latitude survey data within 1of the Galactic Centre (GC) were searched for pulsars using the Fast Folding Algorithm (FFA). Unlike traditional Fast Fourier…
A MeerKAT view of the pulsars in the globular cluster NGC 6522
F. Abbate, A. Ridolfi, P. C. C. Freire +11
We present the results of observations aimed at discovering and studying pulsars in the core-collapsed globular cluster (GC) NGC 6522 performed by the MeerTIME and TRAPUM Large Sur…
The MPIfR-MeerKAT Galactic Plane Survey II. The eccentric double neutron star system PSR J1208-5936 and a neutron star merger rate update
M. Colom i Bernadich, V. Balakrishnan, E. Barr +16
The MMGPS-L is the most sensitive pulsar survey in the Southern Hemisphere. We present a follow-up study of one of these new discoveries, PSR J1208-5936, a 28.71-ms recycled pulsar…
PulsarX: a new pulsar searching package -I. A high performance folding program for pulsar surveys
Yunpeng Men, Ewan Barr, C. J. Clark +2
Pulsar surveys with modern radio telescopes are becoming increasingly computationally demanding. This is particularly true for wide field-of-view pulsar surveys with radio interfer…
Discovery of an Extremely Intermittent Periodic Radio Source
M. P. Surnis, K. M. Rajwade, B. W. Stappers +12
We report the serendipitous discovery of an extremely intermittent radio pulsar, PSR J1710-3452, with a relatively long spin period of 10.4 s. The object was discovered through the…
MeerKAT caught a Mini Mouse: serendipitous detection of a young radio pulsar escaping its birth sit
S. E. Motta, J. D. Turner, B. Stappers +4
In MeerKAT observations pointed at a Galactic X-ray binary located on the Galactic plane we serendipitously discovered a radio nebula with cometary-like morphology. The feature, wh…
The MPIfR-MeerKAT Galactic Plane survey I -- System setup and early results
P. V. Padmanabh, E. D. Barr, S. S. Sridhar +30
Galactic plane radio surveys play a key role in improving our understanding of a wide range of astrophysical phenomena. Performing such a survey using the latest interferometric te…
Tied-Array Beam Localisation of Radio Transients and Pulsars
M. C. Bezuidenhout, C. J. Clark, R. P. Breton +8
Multi-element interferometers such as MeerKAT, which observe with high time resolution and have a wide field-of-view, provide an ideal opportunity to perform real-time, untargeted…
PSR~J19105959A: A rare gravitational laboratory for testing white dwarf models
A. Corongiu, V. Venkatraman Krishnan, P. C. C. Freire +21
PSRJ1910-5959A (J1910A) is a binary millisecond pulsar in a 0.837 day circular orbit around a helium white dwarf (HeWD) companion. This pulsar is located 6.3 arcmin away from the c…
A sample of Fast Radio Bursts discovered and localised with MeerTRAP at the MeerKAT telescope
F. Jankowski, M. C. Bezuidenhout, M. Caleb +14
We present a sample of well-localised Fast Radio Bursts (FRBs) discovered by the MeerTRAP project at the MeerKAT telescope in South Africa. We discovered the three FRBs in single c…
FRB 20210405I: a nearby Fast Radio Burst localised to sub-arcsecond precision with MeerKAT
Laura Nicole Driessen, Ewan Barr, David Buckley +19
We present the first sub-arcsecond localised Fast Radio Burst (FRB) detected using MeerKAT. FRB 20210405I was detected in the incoherent beam using the MeerTRAP pipeline on 2021 Ap…
A sub-arcsec localised fast radio burst with a significant host galaxy dispersion measure contribution
M. Caleb, L. N. Driessen, A. C. Gordon +29
We present the discovery of FRB 20210410D, with the MeerKAT radio interferometer in South Africa, as part of the MeerTRAP commensal project. FRB 20210410D has a dispersion measure…
Discovery of 37 new pulsars through GPU-accelerated reprocessing of archival data of the Parkes Multibeam Pulsar Survey
R. Sengar, M. Bailes, V. Balakrishnan +7
We present the discovery of 37 pulsars from 20 years old archival data of the Parkes Multibeam Pulsar Survey using a new FFT-based search pipeline optimised for discovering…
Neutron star mass estimates from gamma-ray eclipses in spider millisecond pulsar binaries
C. J. Clark, M. Kerr, E. D. Barr +26
Reliable neutron star mass measurements are key to determining the equation-of-state of cold nuclear matter, but these are rare. "Black Widows" and "Redbacks" are compact binaries…
