Kerr-CFT and gravitational perturbations
Oscar J. C. Dias, Harvey S. Reall, Jorge E. Santos
Motivated by the Kerr-CFT conjecture, we investigate perturbations of the near-horizon extreme Kerr spacetime. The Teukolsky equation for a massless field of arbitrary spin is solv…
Bifurcation of Plasma Balls and Black Holes to Lobed Configurations
Vitor Cardoso, Oscar J. C. Dias
At high energy densities any quantum field theory is expected to have an effective hydrodynamic description. When combined with the gravity/gauge duality an unified picture emerges…
Dyonic AdS black holes from magnetohydrodynamics
Marco M. Caldarelli, Oscar J. C. Dias, Dietmar Klemm
We use the AdS/CFT correspondence to argue that large dyonic black holes in anti-de Sitter spacetime are dual to stationary solutions of the equations of relativistic magnetohydrod…
Black Holes as Lumps of Fluid
Marco M. Caldarelli, Oscar J. C. Dias, Roberto Emparan +1
The old suggestive observation that black holes often resemble lumps of fluid has recently been taken beyond the level of an analogy to a precise duality. We investigate aspects of…
Gravitational radiation in d>4 from effective field theory
Vitor Cardoso, Oscar J. C. Dias, Pau Figueras
Some years ago, a new powerful technique, known as the Classical Effective Field Theory, was proposed to describe classical phenomena in gravitational systems. Here we show how thi…
Microscopic Theory of Black Hole Superradiance
Oscar J. C. Dias, Roberto Emparan, Alessandro Maccarrone
We study how black hole superradiance appears in string microscopic models of rotating black holes. In order to disentangle superradiance from finite-temperature effects, we consid…
