Quasinormal modes are eigenmodes of dissipative systems. Perturbations of classical
gravitational backgrounds involving black holes or branes naturally lead to quasinormal …

In this review we summarize, expand, and set in context recent developments on the
thermodynamics of black holes in extended phase space, where the cosmological constant …

Light bosonic degrees of freedom have become a serious candidate for dark matter, which
seems to pervade our entire Universe. The evolution of these fields around curved …

A bstract We study black hole linear perturbation theory in a four-dimensional Schwarzschild
(anti) de Sitter background. When dealing with a positive cosmological constant, the …

Any spacetime containing a degenerate Killing horizon, such as an extremal black hole,
possesses a well-defined notion of a near-horizon geometry. We review such near-horizon …

A bstract Black holes in anti-de Sitter (AdS) backgrounds play a pivotal role in the
gauge/gravity duality where they determine, among other things, the approach to equilibrium …

We present the first examples of black holes with only one Killing field. The solutions
describe five dimensional AdS black holes with scalar hair. The black holes are neither …

We study the propagation of charged scalar fields in the background of 2+ 1-dimensional
Coulomb-like AdS black holes, and we show that such propagation is unstable under …

A bstract Employing the novel exact dictionary between the laws of extended black hole
thermodynamics and the laws of the dual CFT, we study the extended thermodynamics for …

A bstract We investigate the weak cosmic censorship conjecture in Kerr-(anti-) de Sitter
black holes under the scattering of a scalar field. We test the conjecture in terms of whether …
