Searches for signatures of ultra-light axion dark matter in polarimetry data of the European Pulsar Timing Array
N. K. Porayko, P. Usynina, J. Terol-Calvo +74
Ultra-light axion-like particles (ALPs) can be a viable solution to the dark matter problem. The scalar field associated with ALPs, coupled to the electromagnetic field, acts as an…
The MeerKAT Pulsar Timing Array: The first search for gravitational waves with the MeerKAT radio telescope
Matthew T. Miles, Ryan M. Shannon, Daniel J. Reardon +22
Pulsar Timing Arrays search for nanohertz-frequency gravitational waves by regularly observing ensembles of millisecond pulsars over many years to look for correlated timing residu…
The MeerKAT Pulsar Timing Array: The -year data release and the noise and stochastic signals of the millisecond pulsar population
Matthew T. Miles, Ryan M. Shannon, Daniel J. Reardon +21
Pulsar timing arrays are ensembles of regularly observed millisecond pulsars timed to high precision. Each pulsar in an array could be affected by a suite of noise processes, most…
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
E. Carli, L. Levin, B. W. Stappers +10
The Small and Large Magellanic Clouds are the only galaxies outside our own in which radio pulsars have been discovered to date. The sensitivity of the MeerKAT radio interferometer…
Triple trouble with PSR J1618-3921: Mass measurements and orbital dynamics of an eccentric millisecond pulsar
K. Grunthal, V. Venkatraman Krishnan, P. C. C. Freire +11
PSR J1618-3921 is one of five known millisecond pulsars (MSPs) in eccentric orbits (eMPSs) located in the Galactic plane, whose formation is poorly understood. Earlier studies of t…
