kerr black holes as Particle Accelerators to arbitrarily high energy
Physical Review Letters, 2009Co-Authors: Maximo Banados, Joseph Silk, Stephen M WestAbstract:We show that intermediate mass black holes conjectured to be the early precursors of supermassive black holes and surrounded by relic cold dark matter density spikes can act as Particle Accelerators with collisions, in principle, at arbitrarily high center-of-mass energies in the case of Kerr black holes. While the ejecta from such interactions will be highly redshifted, we may anticipate the possibility of a unique probe of Planck-scale physics.

non extremal kerr black holes as Particle Accelerators
Physical Review D, 2011Co-Authors: Sijie Gao, Changchun ZhongAbstract:It has been shown that extremal Kerr black holes can be used as Particle Accelerators and arbitrarily high energy may be obtained near the event horizon. We study Particle collisions near the event horizon (outer horizon) and Cauchy horizon (inner horizon) of a non-extremal Kerr black hole. Firstly, we provide a general proof showing that Particles cannot collide with arbitrarily high energies at the outter horizon. Secondly, we show that ultraenergetic collisions can occur near the inner horizon of a Kerr black hole with any spin parameter a. PACS numbers: 04.70.Bw, 97.60.Lf
