Interplanetary scintillation-informed heliospheric modelling for the MeerKAT Pulsar Timing Array 4.5 yr dataset
Saurav Mishra, Daniel J. Reardon, Andrew Zic +9
Heliospheric density variations impart delays on pulse times of arrivals from millisecond pulsars. Improper modelling of these variations may affect gravitational wave detection an…

A joint MeerKAT and Parkes view of Omega Centauri: New TRAPUM Searches and Pulsar Timing
Miquel Colom i Bernadich, Shi Dai, Federico Abbate +27
Millisecond pulsars (MSPs) are powerful probes of globular clusters (GCs), tracing stellar evolution, cluster dynamics, and the local gravitational potential. We investigate the MS…

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…
