Optimising gravitational-wave sky maps for pulsar timing arrays

Astronomy & Astrophysics
Context. 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 to understanding how it is formed, since anisotropy is a tracer ...

Future Space-based γ-Ray Pulsar Timing Arrays

The Astrophysical Journal Letters
Radio pulsar timing arrays (PTAs) of millisecond pulsars (MSPs) are beginning to detect nHz gravitational waves (GWs). MSPs are bright γ -ray emitters, and all-sky monitoring of ∼100 MSPs with the Fermi Large Area Telescope enables the γ -ray PTA (GPTA).

Upper Limits on Microhertz Gravitational Waves from Supermassive Black Hole Binaries Using PSR J1909–3744 Data from the Second IPTA Data Release

The Astrophysical Journal
We present the results of a search for gravitational waves (GWs) from individual sources using high-cadence observations of PSR J1909−3744 obtained during an intensive observing campaign with the International Pulsar Timing Array second data release ...

Pulsar Timing Arrays Require Hierarchical Models

The Astrophysical Journal Supplement Series
Pulsar timing array (PTA) projects have found evidence of a stochastic background of gravitational waves (GWB) using data from an ensemble of pulsars. In the literature, minimal assumptions are made about the signal and noise processes that affect data ...
