Detected stochastic gravitational waves and subsolar-mass primordial black holes

Physical Review D, 2023
Multiple pulsar timing array (PTA) collaborations recently announced the evidence of common-spectral processes caused by gravitational waves (GWs). These can be the stochastic GW background and its origin may be astrophysical and/or cosmological.
