Sonia Díaz, T Thongmeearkom, A Phosrisom, R. P. Breton, M. Burgay , et al. · 2025

We report the discovery of a new black-widow millisecond pulsar, PSR J1544-2555, associated with the Fermi-LAT source 4FGL J1544.2-2554. Optical, radio, and gamma-ray observations confirmed its nature as a compact spider binary system. Opt…

Radio and gamma-ray timing of TRAPUM L-band Fermi pulsar survey discoveries Open

M. Burgay, L. Nieder, C. J. Clark, P. C. C. Freire, S. Buchner , et al. · 2024

This paper presents the results of a joint radio and gamma-ray timing campaign on the nine millisecond pulsars (MSPs) discovered as part of the L -band targeted survey of Fermi -LAT sources performed in the context of the Transients and Pu…

The TRAPUM Small Magellanic Cloud pulsar survey with MeerKAT – II. Nine new radio timing solutions and glitches from young pulsars Open

E Carli, D. Antonopoulou, M. Burgay, M. J. Keith, L. Levin , et al. · 2024

We report new radio timing solutions from a 3-yr observing campaign conducted with the MeerKAT and Murriyang telescopes for nine Small Magellanic Cloud pulsars, increasing the number of characterized rotation-powered extragalactic pulsars …

A targeted radio pulsar survey of redback candidates with MeerKAT Open

T Thongmeearkom, C. J. Clark, R. P. Breton, M. Burgay, L. Nieder , et al. · 2024

Redbacks are millisecond pulsar binaries with low-mass, irradiated companions. These systems have a rich phenomenology that can be used to probe binary evolution models, pulsar wind physics, and the neutron star mass distribution. A number…
