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 NANOGrav 12.5-year Data Set: Chromatic Noise Characterization & Mitigation with Time-Domain Kernels
Jeffrey S. Hazboun, Joseph Simon, Jeremy Baier +64
Pulsar timing arrays (PTAs) have recently entered the detection era, quickly moving beyond the goal of simply improving sensitivity at the lowest frequencies for the sake of observ…
Expectations for the first supermassive black-hole binary resolved by PTAs I: Model efficacy
Levi Schult, Polina Petrov, Stephen R. Taylor +4
One of the most promising targets for Pulsar Timing Arrays (PTAs) is identifying an individual supermassive black hole binary (SMBHB) out of the population of binaries theorized to…
Expectations for the first supermassive black-hole binary resolved by PTAs II: Milestones for binary characterization
Polina Petrov, Levi Schult, Stephen R. Taylor +4
Following the recent evidence for a gravitational wave (GW) background found by pulsar timing array (PTA) experiments, the next major science milestone is resolving individual supe…
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…
