Discovery of Two Consecutive Profile Change Events in the Millisecond Pulsar PSR J0437-4715
Rami F. Mandow, Andrew Zic, J. R. Dawson +19
The closest and brightest millisecond pulsar (MSP), PSR J0437-4715, is a high-priority pulsar for precision timing experiments, including the Parkes Pulsar Timing Array (PPTA) proj…
Nanohertz Gravitational-Wave Constraints on Supermassive Binary Black Holes at Cosmic Dawn
Yiqin Chen, Shi-Yi Zhao, Xingjiang Zhu +16
Standard continuous gravitational-wave searches with pulsar timing arrays (PTAs) neglect cosmological redshift, restricting their applicability to the local Universe. We introduce…
JUG: JAX-based Unified pulsar timinG
Matthew T. Miles, Stephen R. Taylor, Matthew Bailes +14
We present JUG (JAX-based Unified pulsar timinG), a JAX-based, fully independent pulsar timing package emphasising speed and ease of use, designed to confidently handle the increas…
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…
Targeted search for eccentric supermassive binary black holes in OJ 287 and nearby galaxy clusters with PPTA DR3
Shi-Yi Zhao, Xingjiang Zhu, Jacob Cardinal Tremblay +19
We perform Bayesian targeted searches for continuous gravitational waves from eccentric supermassive binary black holes (SMBBHs) using the Parkes Pulsar Timing Array third data rel…
Searching for Anisotropy in the Gravitational Wave Background Using the Parkes Pulsar Timing Array
Yiqin Chen, Shi-Yi Zhao, Zhi-Zhang Peng +17
In recent years, several pulsar timing array collaborations have reported evidence for a nanohertz gravitational wave background (GWB). Such a background signal could be produced b…
