Elastic shocks in relativistic rigid rods and balls
João L. Costa, José Natário
We study the free boundary problem for the "hard phase" material introduced by Christodoulou, both for rods in (1+1)-dimensional Minkowski spacetime and for spherically symmetric b…
Strong cosmic censorship: The nonlinear story
Raimon Luna, Miguel Zilhão, Vitor Cardoso +2
A satisfactory formulation of the laws of physics entails that the future evolution of a physical system should be determined from appropriate initial conditions. The existence of…
Strong cosmic censorship in charged black-hole spacetimes: still subtle
Vitor Cardoso, Joao L. Costa, Kyriakos Destounis +2
It was recently shown that Strong Cosmic Censorship may be violated in highly charged black-hole spacetimes living in a universe with a positive cosmological constant. Several foll…
Decay of solutions of the wave equation in expanding cosmological spacetimes
João L. Costa, José Natário, Pedro Oliveira
We study the decay of solutions of the wave equation in some expanding cosmological spacetimes, namely flat Friedmann-Lemaître-Robertson-Walker (FLRW) models and the cosmological r…
Cosmic no-hair in spherically symmetric black hole spacetimes
João L. Costa, José Natário, Pedro Oliveira
We analyze in detail the geometry and dynamics of the cosmological region arising in spherically symmetric black hole solutions of the Einstein-Maxwell-scalar field system with a p…
