Abstract
Black holes become the most massive objects early in the evolution of
star clusters. Dynamical relaxation then causes them to sink to the
cluster core, where they form binaries which become more tightly bound
by superelastic encounters with other cluster members. Ultimately,
these binaries are ejected from the cluster. The majority of escaping
black-hole binaries have orbital periods short enough and
eccentricities high enough that the emission of gravitational waves
causes them to coalesce within a few billion years. The rate at which
such collisions occur is on the order of 10-7 per year per cubic megaparsec. This implies event rates for gravitational-wave detectors substantially greater than current estimates of the corresponding
rates from neutron-star mergers or black-hole mergers stemming from pure binary evolution.
