Primordial gravitational waves in the nano-Hertz regime and PTA data — towards solving the GW inverse problem

Primordial gravitational waves in the nano-Hertz regime and PTA data — towards solving the GW inverse problem

Abstract In recent years, several pulsar timing array collaborations have reported first hints for a stochastic gravitational wave background at nano-Hertz frequencies. Here we elaborate on the possibility that this signal comes from new physics that leads to the generation of a primordial stochasti...
