The SKAO Pulsar Timing Array

Ryan M. Shannon, N. D. Ramesh Bhat, Aurélien Chalumeau +22

Pulsar timing arrays (PTAs) are ensembles of millisecond pulsars observed for years to decades. The primary goal of PTAs is to study gravitational-wave astronomy at nanohertz frequ…

Optimising gravitational-wave sky maps for pulsar timing arrays

Kathrin Grunthal, David J. Champion, Eric Thrane +3

Pulsar timing arrays (PTAs) have recently reported compelling evidence for the presence of a gravitational-wave background signal. Mapping the gravitational-wave background is key…

The role of distant pulsars in the detectability of continuous gravitational waves

Kathrin Grunthal, Nataliya Porayko, David J. Champion +1

One of the imminent science goals of pulsar timing arrays (PTAs) is the detection of a continuous gravitational wave (CGW) emitted by an individual supermassive black hole binary (…

Optimising the MeerKAT Pulsar Timing Array and towards precision pulsar timing with SKA-mid

Pratyasha Gitika, Ryan M. Shannon, Matthew Bailes +4

Pulsar timing arrays (PTAs) are Galactic-scale nanohertz-frequency gravitational wave (GW) detectors. Recently, several PTAs have found evidence for the presence of GWs in their da…

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…
