Inflationary interpretation of the gravitational-wave signal in the European Pulsar Timing Array DR2 with constraints
Philippe Turgeon, Chiara Caprini, Anton Chudaykin +5
The second data release of the European Pulsar Timing Array (EPTA) collaboration provides evidence for the presence of a gravitational-wave (GW) background. In this work, we explor…
