The impact of large-scale galaxy clustering on the variance of the Hellings-Downs correlation: numerical results
Nastassia Grimm, Martin Pijnenburg, Giulia Cusin +1
Pulsar timing array experiments have recently found evidence for a stochastic gravitational wave (GW) background, which induces correlations among pulsar timing residuals described…

Measuring anisotropies in the PTA band with cross-correlations
Giulia Cusin, Cyril Pitrou, Martin Pijnenburg +1
The astrophysical gravitational wave background in the nanohertz (nHz) band is expected to be primarily composed of the superposition of signals from binaries of supermassive black…

The impact of large-scale galaxy clustering on the variance of the Hellings-Downs correlation: theoretical framework
Nastassia Grimm, Martin Pijnenburg, Giulia Cusin +1
While pulsar timing array experiments have recently found evidence for the existence of a stochastic gravitational wave (GW) background, its origin is still unclear. If this backgr…
