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…
Pulsar Timing Array Sensitivity to Anisotropy: Empirical Sensitivity Curves, Scaling Relations, and the Multi-Resolution Pixel Basis
Taha T. Moursy, Nihan S. Pol, Gabriella Agazie +115
We quantify pulsar timing array (PTA) sensitivity to anisotropy in the gravitational wave background using the cross-correlation based Fisher information matrix in the pixel and sp…
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…
A transdimensional sampling framework for pulsar timing noise modelling
Valentina Di Marco, Nir Guttman, Matthew T. Miles +3
A careful characterisation of the noise processes in pulsar timing data is a prerequisite for pulsar timing array experiments. While single-pulsar noise analyses are crucial for bo…
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…
Improving pulsar-timing solutions through dynamic pulse fitting
Rowina S. Nathan, Matthew T. Miles, Gregory Ashton +5
Precision pulsar timing is integral to the detection of the nanohertz stochastic gravitational-wave background as well as understanding the physics of neutron stars. Conventional p…
Toward robust detections of nanohertz gravitational waves
Valentina Di Marco, Andrew Zic, Matthew T. Miles +3
The recent observation of a common red-noise process in pulsar timing arrays (PTAs) suggests that the detection of nanohertz gravitational waves might be around the corner. However…
