An updated constraint for the Gravitational Wave Background from the Gamma-ray Pulsar Timing Array

Serena Valtolina, Colin J. Clark, Rutger van Haasteren +5

Fermi LAT observations of gamma-ray pulsars can be used to build a pulsar timing array (PTA) experiment to search for gravitational wave (GW) signals at nanohertz frequencies. At t…

The polarimetric response of the Nançay Radio Telescope and its impact on precision pulsar timing

Lucas Guillemot, Willem van Straten, Ismaël Cognard +3

In \citet{Guillemot2023} we presented a new method for calibrating pulsar observations conducted with the Nançay decimetric Radio Telescope (NRT), which significantly improved NRT…

Rapid Construction of Joint Pulsar Timing Array Datasets: The Lite Method

Bjorn Larsen, Chiara M. F. Mingarelli, Paul T. Baker +41

The International Pulsar Timing Array (IPTA)'s second data release (IPTA DR2) combines decades of observations of 65 millisecond pulsars from 7 radio telescopes. IPTA datasets shou…

Impact of the observation frequency coverage on the significance of a gravitational wave background detection in PTA data

Irene Ferranti, Mikel Falxa, Alberto Sesana +8

Pulsar Timing Array (PTA) collaborations gather high-precision timing measurements of pulsars with the aim of detecting gravitational wave (GW) signals. A major challenge lies in t…

Reading signatures of supermassive binary black holes in pulsar timing array observations

Boris Goncharov, Shubhit Sardana, A. Sesana +10

We find the inferred properties of the putative gravitational wave background in the second data release of the European Pulsar Timing Array to be in better agreement with theoreti…
