Abstract
We consider the high-speed collision of a particle with a black hole, and compute the gravitational wave spectra and total radiated energy, for both rotating and non-rotating holes. Some interesting properties of the energy spectrum characterize these processes, such as universal zero frequency limit and a power-law dependence on the multipole index. Making the extrapolation to the two black hole collision at the speed of light case, we conclude that this is the most efficient gravitational wave generator in the Universe.
