The SKAO Pulsar Timing Array

Ryan M. Shannon, N. D. Ramesh Bhat, Aurélien Chalumeau +22

Pulsar timing arrays (PTAs) are ensembles of millisecond pulsars observed for years to decades. The primary goal of PTAs is to study gravitational-wave astronomy at nanohertz frequ…

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…

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…

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…

Dissecting the nanoHz gravitational wave sky: frequency-correlated anisotropy induced by eccentric supermassive black hole binaries

Beatrice Eleonora Moreschi, Serena Valtolina, Alberto Sesana +5

Revealing the nature of the nanoHz gravitational wave (GW) signal recently reported by Pulsar Timing Arrays (PTAs) collaborations around the world is the next goal of low-frequency…
