Enhanced Detectability of Spinning Primordial Black Holes

Understand

Primordial black holes which are produced during an epoch of matter domination are expected to spin rapidly.

• It is shown that this leads to an enhancement of the detectability of the stochastic gravitational-wave background from their mergers.
• For a specific model, we explicitly demonstrate that this yields a $50\,\%$ increase of the gravitational-wave amplitude as compared to the non-spinning case.
