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…
Deep Neural Emulation of the Supermassive Black-hole Binary Population
Nima Laal, Stephen R. Taylor, Luke Zoltan Kelley +13
While supermassive black-hole (SMBH)-binaries are not the only viable source for the low-frequency gravitational wave background (GWB) signal evidenced by the most recent pulsar ti…
Solving the PTA Data Analysis Problem with a Global Gibbs Scheme
Nima Laal, Stephen R. Taylor, Rutger van Haasteren +2
The announcement in the summer of 2023 about the discovery of evidence for a gravitational wave background (GWB) using pulsar timing arrays (PTAs) has ignited both the PTA and the…
Exploring the Capabilities of Gibbs Sampling in Pulsar Timing Arrays
Nima Laal, William G Lamb, Joseph D. Romano +3
We explore the use of Gibbs sampling in estimating the noise properties of individual pulsars and illustrate its effectiveness using the NANOGrav 11-year data set. We find that Gib…
