Scattering Cross Section and Stability of Global Monopoles
J. P. M. Pitelli, V. S. Barroso, Maurício Richartz
We study the scattering of scalar waves propagating on the global monopole background. Since the scalar wave operator in this topological defect is not essentially self-adjoint, it…

Synchronous frequencies of extremal Kerr black holes: resonances, scattering and stability
Maurício Richartz, Carlos A. R. Herdeiro, Emanuele Berti
The characteristic damping times of the natural oscillations of a Kerr black hole become arbitrarily large as the extremal limit is approached. This behavior is associated with the…
