Pulsar timing array Inference of the Nanohertz Gravitational wave Universe
We are on the verge of the next big breakthrough in gravitational wave (GW) astronomy: namely the detection of a nano-Hz GW signal with Pulsar Timing Arrays (PTAs). Within the next few years nano-Hz GWs will be established as a completely new window on our Universe, unlocking an unprecedented opportunity to unveil its secrets. The signal is anticipated to come from a cosmic population of supermassive black hole binaries (SMBHBs), which are a fundamental, yet observationally missing, piece in the process of structure formation and galaxy evolution. However, alternative Early Universe origins, including backgrounds arising from inflation or phase transitions, cannot be dismissed a priori. To…
