Galactic Centre Pulsars with the SKAO

F. Abbate, A. Carleo, S. Chatterjee +18

The detection of a pulsar closely orbiting our Galaxy's supermassive black hole - Sagittarius~A* - is one of the ultimate prizes in pulsar astrophysics. The relativistic effects ex…

Discovery of two new millisecond pulsars towards the Galactic bulge

J. Berteaud, F. Calore, M. Clavel +13

The mysterious Galactic Center Excess of gamma rays could be explained by a large population of millisecond pulsars hiding in the Galactic bulge, too faint to be detected as indivi…

Pulsars in Globular Clusters With the SKAO

Manjari Bagchi, Federico Abbate, Vishnu Balakrishnan +15

Because of their extreme stellar densities, globular clusters are highly efficient factories of X-ray binaries and radio pulsars: per unit of stellar mass, they contain about 1000…
