The Great Escape: Tunneling out of Microstate Geometries
Iosif Bena, Felicity Eperon, Pierre Heidmann +1
We compute the quasi-normal frequencies of scalars in asymptotically-flat microstate geometries that have the same charge as a D1-D5-P black hole, but whose long BTZ-like throat en…
Plausible scenario for a generic violation of the weak cosmic censorship conjecture in asymptotically flat four dimensions
Felicity C. Eperon, Bogdan Ganchev, Jorge E. Santos
We present a plausible counterexample to the weak cosmic censorship conjecture in the four-dimensional Einstein-Scalar theory with asymptotically flat boundary conditions. Our setu…
Predictability of subluminal and superluminal wave equations
Felicity C. Eperon, Harvey S. Reall, Jan J. Sbierski
It is sometimes claimed that Lorentz invariant wave equations which allow superluminal propagation exhibit worse predictability than subluminal equations. To investigate this, we s…
Strong cosmic censorship in de Sitter space
Oscar J. C. Dias, Felicity C. Eperon, Harvey S. Reall +1
Recent work indicates that the strong cosmic censorship hypothesis is violated by nearly extremal Reissner-Nordstrom-de Sitter black holes. It was argued that perturbations of such…
Geodesics in supersymmetric microstate geometries
Felicity C. Eperon
It has been argued that supersymmetric microstate geometries are classically unstable. One argument for instability involves considering the motion of a massive particle near the e…
Instability of supersymmetric microstate geometries
Felicity C. Eperon, Harvey S. Reall, Jorge E. Santos
We investigate the classical stability of supersymmetric, asymptotically flat, microstate geometries with five non-compact dimensions. Such geometries admit an "evanescent ergosurf…
