Advanced LIGO's discovery of gravitational-wave events is stimulating extensive studies on the origin of binary black holes. Assuming that the gravitational-wave events can be explained by binary primordial black hole mergers, we utilize the upper limits on the stochastic gravitational-wave background given by Advanced LIGO as a new observational window to independently constrain the abundance of primordial black holes in dark matter. We show that Advanced LIGO's first observation run gives the…

Stochastic Gravitational-Wave Background due to Primordial Binary Black Hole Mergers.

TLDR
The stochastic background arising from the incoherent superposition of such primordial binary black hole systems in the Universe is computed and it is concluded that constraining the dark matter component in the form of black holes using stochastically gravitational-wave background measurements will be very challenging.
