Massive quantum divergence on the Cauchy horizon of a black hole
Marc Casals, Lorenzo Pisani, Peter Taylor
We investigate a quantum massive scalar field in the interior of a charged and spherically-symmetric (Reissner-Nordström) black hole. We examine the behaviour for varying values of…
Calculation of a regularized Teukolsky Green function in Schwarzschild spacetime
David Q. Aruquipa, Marc Casals, Brien C. Nolan
We obtain exact expressions for various factors involved in the Hadamard form of the retarded Green function for the (Bardeen-Press-)Teukolsky equation on Schwarzschild spacetime.…
Horizon Multipole Moments of a Kerr Black Hole
Eric Gourgoulhon, Alexandre Le Tiec, Marc Casals
The horizon multipole moments of a Kerr black hole are computed from two distinct definitions that have been proposed in the literature. The first one [Ashtekar et al., Class. Quan…
Infinite quantum twisting at the Cauchy horizon of rotating black holes
Christiane Klein, Mojgan Soltani, Marc Casals +1
We present a numerical calculation of the expectation value of the quantum angular-momentum current flux density for a scalar field in the Unruh state near the inner horizon of a K…
Brane decay of a (4+n)-dimensional rotating black hole: spin-0 particles
G. Duffy, C. Harris, P. Kanti +1
In this work, we study the `scalar channel' of the emission of Hawking radiation from a (4+n)-dimensional, rotating black hole on the brane. We numerically solve both the radial an…
