The first MeerKAT S-band globular cluster pulsar survey

Rouhin Nag, Marta Burgay, Alessandro Ridolfi +19

Globular clusters are efficient factories of recycled pulsars, but searches toward high-dispersion-measure (DM) clusters can be strongly limited near 1 GHz by dispersive smearing a…

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…

Variability of Sagittarius A* at 3 GHz on minute-scale with MeerKAT

K. Kaur, I. Rammala-Zitha, A. Basu +21

The supermassive black hole Sagittarius A* (Sgr A*) exhibits temporal and spectral variability across the electromagnetic spectrum. However, variability at radio frequencies below…

Pulsar Discoveries from the TRAPUM UHF Survey of Fermi-LAT Sources

Tinn Thongmeearkom, Colin J. Clark, Rene P. Breton +25

The Fermi Large Area Telescope (LAT) provides advantages for radio pulsar searches by enabling efficient target selection. We can confidently point radio telescopes to the position…

A joint MeerKAT and Parkes view of Omega Centauri: New TRAPUM Searches and Pulsar Timing

Miquel Colom i Bernadich, Shi Dai, Federico Abbate +27

Millisecond pulsars (MSPs) are powerful probes of globular clusters (GCs), tracing stellar evolution, cluster dynamics, and the local gravitational potential. We investigate the MS…

PSR J00247204ai: a massive, eccentric binary system in the globular cluster 47 Tucanae

D. Risbud, A. Ridolfi, P. C. C. Freire +9

In this paper we present PSR J00247204ai, a 13.026-ms binary pulsar recently discovered in the globular cluster 47 Tucanae by the MeerKAT radio telescope. This is the slowest sp…
