When spacetime vibrates: An introduction to gravitational waves
José P. S. Lemos
This article presents a comprehensive analysis of the physics of gravitational waves, exploring both the theoretical foundations and the most recent experimental advances. After a…
Traversable wormholes with double layer thin shells in quadratic gravity
Joao Luís Rosa, Rui André, José P. S. Lemos
In quadratic gravity, the junction conditions are six and permit the appearance of double layer thin shells. Double layers arise typically in theories with dipoles, i.e., two oppos…
Black holes and hot shells in the Euclidean path integral approach to quantum gravity
José P. S. Lemos, O. B. Zaslavskii
We study a spherical black hole surrounded by a hot self-gravitating thin shell in the canonical ensemble, i.e., a black hole and a hot shell inside a heat reservoir acting as a bo…
Relativistic cosmology and intrinsic spin of matter: Results and theorems in Einstein-Cartan theory
Paulo Luz, José P. S. Lemos
We start by presenting the general set of structure equations for the 1+3 threading spacetime decomposition in 4 spacetime dimensions, valid for any theory of gravitation based on…
Normal modes of Proca fields in AdS spacetime
Tiago V. Fernandes, David Hilditch, José P. S. Lemos +1
A normal mode analysis for Proca fields in the anti-de Sitter (AdS) spacetime is given. It is found that the equations for the Proca field can be decoupled analytically. This is pe…
Stability of electrically charged stars, regular black holes, quasiblack holes, and quasinonblack holes
Angel D. D. Masa, José P. S. Lemos, Vilson T. Zanchin
The stability of a class of electrically charged fluid spheres under radial perturbations is studied. Among these spheres there are regular stars, overcharged tension stars, regula…
