Testing Gravity with Binary Pulsars in the SKA Era

V. Venkatraman Krishnan, L. Shao, V. Balakrishnan +21

Binary (and trinary) radio pulsars are natural laboratories in space for understanding gravity in the strong field regime, with many unique and precise tests carried out so far, in…

A simple optimisation for the MeerKAT Pulsar Timing Array

Hannah Middleton, Ryan M. Shannon, Matthew Bailes +9

The goal of the MeerKAT radio telescope's pulsar timing array programme (MPTA) is the detection of gravitational waves (GWs) of nanohertz frequencies. Evidence for such a signal wa…

Bow Shock and Local Bubble Plasma Unveiled by the Scintillating Millisecond Pulsar J04374715

Daniel J. Reardon, Robert Main, Stella Koch Ocker +10

The ionized interstellar medium contains au-scale (and below) structures that scatter radio waves from pulsars, resulting in scintillation. Power spectral analysis of scintillation…

The MeerKAT Pulsar Timing Array: Maps of the gravitational-wave sky with the 4.5 year data release

Kathrin Grunthal, Rowina S. Nathan, Eric Thrane +16

In an accompanying publication, the MeerKAT Pulsar Timing Array (MPTA) collaboration reports tentative evidence for the presence of a stochastic gravitational-wave background, foll…

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…
