Towards the detection of the nanohertz gravitational-wave background

Munich, Germany (SPX) Oct 28, 2021 The European Pulsar Timing Array (EPTA) is a scientific collaboration bringing together teams of astronomers around the largest European radio telescopes, as well as groups specialized in data analysis and modelling of gravitational-wave (GW) signals. It has published a detailed analysis of a candidate signal for the since-long sought gravitational-wave background (GWB) due to in-spiraling super
