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…
