The first MeerKAT S-band globular cluster pulsar survey

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…
Discovery of an Extremely Intermittent Periodic Radio Source

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…
