Theoretical interpretations of the pulsar timing data recently released by NANOGrav – Phys.org

The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) is a gravitational-wave detector that monitors areas in the vicinity of Earth using a network of pulsars (i.e., clock-like stars). At the end of 2020, the NANOGrav collaboration gathered evidence of fluctuations in the timing data of 45 pulsars, which could be compatible with a stochastic gravitational wave background (SGWB) signal at nanohertz frequencies.
These gravitational waves could potentially be linked to the mergers…
