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…
On the triple nature of the PSR J0435+3233 system
Paulo C. C. Freire, Colin J. Clark, Cees G. Bassa +4
Context. The recent pulsar timing ephemeris of PSR J0435+3233 indicates that this millisecond pulsar (MSP) has a spin-down rate that is much higher than observed in other MSPs and…
A new framework for lightning-fast gravitational wave analysis of pulsar timing data
Aiden Gundersen, Rutger van Haasteren, Neil J. Cornish +2
Pulsar timing array data analysis is computationally expensive, limiting the complexity of models which can be studied. As pulsar timing datasets and their respective models grow i…
Evaluating the Fourier Approximation in Pulsar Timing Array Analysis
Yongqi Zhang, Hayden Scholz, Ken D. Olum +53
Pulsar timing arrays search for stochastic processes such as gravitational waves by comparing pulse time of arrival data for millisecond pulsars to expectations from a background w…
The NANOGrav 15 yr Data Set: Impacts of Customized Chromatic Noise Models on Gravitational Wave Analyses
Nikita Agarwal, Gabriella Agazie, Alessandra Amosso +120
We report updated nHz gravitational wave (GW) significance, characterization, and interpretations using the customized chromatic-noise models (CNMs) developed in Larsen, Baier et a…
