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…
Directional Anisotropic Sensitivity Curves for Pulsar Timing Arrays
Daniel J. Oliver, Jeffrey S. Hazboun, Martine Maggi +2
After two decades of observations, pulsar timing array collaborations have reported strong evidence for a stochastic gravitational wave background, most likely sourced by an inspir…
No persuasive evidence yet of gravitational-wave tails from perturbers along the line of sight in LVK observations
Kuba Kopczuk, Ethan Blake, Matthew F. Carney +7
The authors search LIGO‑Virgo‑KAGRA data for gravitational‑wave tail signals, called "glints," using Bayesian model comparison and find no convincing evidence, setting upper limits…
Mitigating the Timing Impact of Anomalous Pulse Profile Shape Variability in PSR J1713+0747 with Gaussian Component Modeling
Shania A. Nichols, Michael T. Lam, Gabriella Agazie +31
The paper presents a Gaussian component modeling technique to track and correct sudden pulse‑shape changes in the millisecond pulsar PSR J1713+0747, preserving high‑precision timin…
The NANOGrav 15 yr Data Set: Customized Chromatic Noise Models
Bjorn Larsen, Jeremy G. Baier, Daniel J. Oliver +53
Pulsar timing arrays conduct low-frequency gravitational wave searches, which require comprehensive accounting of various noise sources to achieve robust results. Interstellar prop…
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…
