Curvature and dynamical spacetimes: can we peer into the quantum regime?
Vitor Cardoso, David Hilditch, Krinio Marouda +2
Stationary compact astrophysical objects such as black holes and neutron stars behave as classical systems from the gravitational point of view. Their (observable) curvature is eve…
Explicit formulas and decay rates for the solution of the wave equation in cosmological spacetimes
Jose Natario, Flavio Rossetti
We obtain explicit formulas for the solution of the wave equation in certain Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetimes. Our method, pioneered by Klainerman and Sarnak,…
Extrinsic black hole uniqueness in pure Lovelock gravity
Levi Lopes de Lima, Frederico Girão, José Natário
We define a notion of extrinsic black hole in pure Lovelock gravity of degree which captures the essential features of the so-called Lovelock-Schwarzschild solutions, viewed as…
Poynting vector, super-Poynting vector, and principal observers in electromagnetism and general relativity
Lode Wylleman, L. Filipe O. Costa, José Natário
In electromagnetism, the concept of Poynting vector as measured by an observer is well known. A mathematical analogue in general relativity is the super-Poynting vector of the Weyl…
Proof of the weak cosmic censorship conjecture for several extremal black holes
Jéssica Gonçalves, José Natário
We show explicitly, for different types of extremal black holes, that test fields satisfying the null energy condition at the event horizon cannot violate the weak cosmic censorshi…
Gravitomagnetism in the Lewis cylindrical metrics
L. Filipe O. Costa, José Natário, N. O. Santos
The Lewis solutions describe the exterior gravitational field produced by infinitely long rotating cylinders, and are useful models for global gravitational effects. When the metri…
