Abstract
In this paper I consider the collision of black holes with parallel spins using first order perturbation theory of rotating black holes (the Teukolsky formalism). The black holes are assumed to be close to each other, initially nonboosted and spinning slowly. I estimate the properties of the gravitational radiation released from such a collision. The same problem was studied recently by Gleiser and Dominguez [Phys. Rev. D 65, 064018 (2002)] in the context of the Zerilli perturbation formalism and my results for waveforms, energy, and angular momentum radiated agree very well with the results presented in that work.
