On the instability regime of the rotating Kerr spacetime to massive
scalar perturbations    [PDF]

The instability of rotating Kerr black holes due to massive scalar perturbations is investigated. It is well known that a bosonic field impinging on a Kerr black hole can be amplified as it scatters off the hole. This superradiant scattering occurs for frequencies in the range $\omegaView original: http://arxiv.org/abs/1205.1872
