Separation of gravitational perturbations of singly spinning Myers-Perry black holes
Jorge E. Santos
Gravitational perturbations of rotating black holes in higher dimensions generally obey coupled partial differential equations. We show that scalar gravitational perturbations inva…
Blackened BPS: the end of the thermal BMN branch
Jorge E. Santos
We study the thermodynamics of the BMN matrix model at large and strong coupling, using its dual black holes in eleven-dimensional supergravity. Within the consistent truncatio…
Holographic Batteries
William D. Biggs, Jorge E. Santos
We study a three-dimensional holographic CFT under the influence of a background electric field on a spacetime containing two black hole horizons. The electric background is fixed…
Scalar QNM spectra of Kerr and Reissner-Nordström revealed by eigenvalue repulsions in Kerr-Newman
Alex Davey, Oscar J. C. Dias, Jorge E. Santos
Recent studies of the gravito-electromagnetic frequency spectra of Kerr-Newman (KN) black holes have revealed two families of quasinormal modes (QNMs), namely photon sphere modes a…
Black hole superradiant instability for massive spin-2 fields
Oscar J. C. Dias, Giuseppe Lingetti, Paolo Pani +1
Due to coherent superradiant amplification, massive bosonic fields can trigger an instability in spinning black holes, tapping their energy and angular momentum and forming macrosc…
Static Black Binaries in de Sitter
Oscar J. C. Dias, Gary W. Gibbons, Jorge E. Santos +1
We construct the first four-dimensional multi-black hole solution of general relativity with a positive cosmological constant. The solution consists of two static black holes whose…
