PSR J05144002A is a binary millisecond pulsar located in the globular cluster NGC 1851. The pulsar has a spin period of 4.99 ms, an orbital period of 18.8 days, and is in a very…
Timing and noise analysis of five millisecond pulsars observed with MeerKAT
M. Chisabi, S. Andrianomena, U. Enwelum +12
Millisecond pulsars (MSPs) in binary systems are precise laboratories for tests of gravity and the physics of dense matter. Their orbits can show relativistic effects that provide…
Radio and gamma-ray timing of TRAPUM L-band Fermi pulsar survey discoveries

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…
MeerKAT observations of pair-plasma induced birefringence in the double pulsar eclipses
M. E. Lower, M. Kramer, S. Johnston +10
PSR J07373039A/B is unique among double neutron star systems. Its near-perfect edge-on orbit causes the fast spinning pulsar A to be eclipsed by the magnetic field of the slow s…
TRAPUM pulsar and transient search in the Sextans A and B galaxies and discovery of background FRB 20210924D
