Binary Black Holes, Gravitational Bursts and the Issue of the Final Spin
Pablo Laguna (Penn State)
The spin of the final black hole in the coalescence of
black holes is determined by the "residual" orbital angular
momentum of the binary. his residual momentum consists of the
orbital angular momentum that the binary is not able to shed before merging.
In this talk, I will briefly review the current status of binary black hole
simulations and present results from a study of the spin
of the final black hole and gravitational bursts in a series of
black hole encounters, ranging from almost direct infall to numerous orbits before
plunge, that exhibit multiple bursts of radiation in the merger process.
