Enhanced Detectability of Spinning Primordial Black Holes
  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.
