Fifteen new millisecond pulsars in 47 Tucanae
W. Chen, D. Risbud, P. C. C. Freire +16
47 Tucanae is one of the largest, brightest, and closest globular clusters to Earth. It hosts an exotic stellar population with stellar dynamics that indicate a complex evolution h…
NGC 1851A: Revealing an ongoing three-body encounter in a dense globular cluster
A. Dutta, P. C. C. Freire, T. Gautam +16
PSR J05144002A is a binary millisecond pulsar located in the globular cluster NGC 1851. The pulsar has a spin period of 4.99 ms, an orbital period of 18.8 days, and is in a very…
The High Time Resolution Universe Pulsar Survey-XIX. A coherent GPU accelerated reprocessing and the discovery of 71 pulsars in the Southern Galactic plane
R. Sengar, M. Bailes, V. Balakrishnan +19
We have conducted a GPU accelerated reprocessing of of the archival data from the High Time Resolution Universe South Low Latitude (HTRU-S LowLat) pulsar survey by impl…
Eighteen new fast radio bursts in the High Time Resolution Universe survey
M. Trudu, A. Possenti, M. Pilia +16
Current observational evidence reveals that fast radio bursts (FRBs) exhibit bandwidths ranging from a few dozen MHz to several GHz. Traditional FRB searches primarily employ match…
Discoveries and Timing of Pulsars in M62
L. Vleeschower, A. Corongiu, B. W. Stappers +14
Using MeerKAT, we have discovered three new millisecond pulsars (MSPs) in the bulge globular cluster M62: M62H, M62I, and M62J. All three are in binary systems, which means all ten…
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…
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…
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…
Discovery of 37 new pulsars through GPU-accelerated reprocessing of archival data of the Parkes Multibeam Pulsar Survey
