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…
A search for pulsars around Sgr A* in the first Event Horizon Telescope dataset
Pablo Torne, Kuo Liu, Ralph P. Eatough +282
The Event Horizon Telescope (EHT) observed in 2017 the supermassive black hole at the center of the Milky Way, Sagittarius A* (Sgr A*), at a frequency of 228.1 GHz (=1.3 mm). Th…
Rotation measure variations in Galactic Centre pulsars
F. Abbate, A. Noutsos, G. Desvignes +8
We report the results of an observational campaign using the Effelsberg 100-m telescope of the pulsars J17462849, J17462850, J17462856 and J17452912 located in the Cent…
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…
Missing for 20 years: MeerKAT re-detects the elusive binary pulsar M30B
Vishnu Balakrishnan, Paulo Freire, Scott Ransom +14
PSR J21402311B is a 13-ms pulsar discovered in 2001 in a 7.8-hour Green Bank Telescope (GBT) observation of the core-collapsed globular cluster M30 and predicted to be in a high…
MeerKAT discovery of 13 new pulsars in Omega Centauri
W. Chen, P. C. C. Freire, A. Ridolfi +21
The most massive globular cluster in our Galaxy, Omega Centauri, is an interesting target for pulsar searches, because of its multiple stellar populations and the intriguing possib…
