Are PTA measurements sensitive to gravitational wave non-Gaussianities?
Chiara Cecchini, Jonas El Gammal, Gabriele Franciolini +1
Observing non-Gaussianities in the timing residuals of Pulsar Timing Arrays (PTAs) has recently attracted attention as a potential discriminator between astrophysical and cosmologi…

Detecting Gravitational-Wave Anisotropies with Simulation-Based Inference
Anna-Malin Lemke, Andrea Mitridate, Thomas Konstandin +2
Over the last five years, multiple Pulsar Timing Array (PTA) collaborations have reported mounting evidence for a gravitational-wave background (GWB) at nanohertz frequencies. Meas…
