Searches for Shapiro delay in seven binary pulsars using the MeerKAT telescope

Mohsen Shamohammadi, Matthew Bailes, Paulo C. C. Freire +14

Precision timing of millisecond pulsars in binary systems enables observers to detect the relativistic Shapiro delay induced by space time curvature. When favourably aligned, this…

Wideband timing of the Parkes Pulsar Timing Array UWL data

Małgorzata Curyło, Timothy T. Pennucci, Matthew Bailes +14

In 2018 an ultra-wide-bandwidth low-frequency (UWL) receiver was installed on the 64-m Parkes Radio Telescope enabling observations with an instantaneous frequency coverage from 70…

The Thousand-Pulsar-Array programme on MeerKAT -- X. Scintillation arcs of 107 pulsars

R. A. Main, A. Parthasarathy, S. Johnston +9

We present the detection of 107 pulsars with interstellar scintillation arcs at 856--1712\,MHz, observed with the MeerKAT Thousand Pulsar Array Programme. Scintillation arcs appear…

A MeerKAT look at the polarization of 47 Tucanae pulsars: magnetic field implications

F. Abbate, A. Possenti, A. Ridolfi +17

We present the polarization profiles of 22 pulsars in the globular cluster 47 Tucanae using observations from the MeerKAT radio telescope at UHF-band (544-1088 MHz) and report prec…

Gravitational signal propagation in the Double Pulsar studied with the MeerKAT telescope

H. Hu, M. Kramer, D. J. Champion +16

The Double Pulsar, PSR J0737-3039A/B, has offered a wealth of gravitational experiments in the strong-field regime, all of which GR has passed with flying colours. In particular, a…

Evaluating the prevalence of spurious correlations in pulsar timing array datasets

Andrew Zic, George Hobbs, R. M. Shannon +13

Pulsar timing array collaborations have recently reported evidence for a noise process with a common spectrum among the millisecond pulsars in the arrays. The spectral properties o…
