Eccentric black hole mergers and zoom-whirl behavior from elliptic
  inspirals to hyperbolic encounters
  We perform a parameter study of non-spinning, equal and unequal mass black
hole binaries on generic, eccentric orbits in numerical relativity. The linear
momentum considered ranges from that of a circular orbit to ten times that
value. We discuss the different manifestations of zoom-whirl behavior in the
hyperbolic and the elliptic regime. The hyperbolic data set applies to
dynamical capture scenarios (e.g. in globular clusters). Evolutions in the
elliptic regime correspond to possible end states of supermassive black hole
binaries. We spot zoom-whirl behavior for eccentricities as low as $e\sim0.5$,
i.e. within the expected range of eccentricities in massive black hole binaries
from galaxy mergers and binaries near galactic centers. The resulting
gravitational waveforms reveal a rich structure, which will effectively break
degeneracies in parameter space improving parameter estimation.
