Asymptotic structure and stability of spatially homogeneous space-times with a positive cosmological constant
Christian Lübbe, Filipe C. Mena
We investigate the future asymptotics of spatially homogeneous space-times with a positive cosmological constant by using and further developing geometric conformal methods in Gene…
Global evolution in spherical symmetry for self-gravitating massive fields
Philippe G. LeFloch, Filipe C. Mena, The-Cang Nguyen
We are interested in the global dynamics of a massive scalar field evolving under its own gravitational field and, in this paper, we study spherically symmetric solutions to Einste…
Improved decay estimates and -asymptotic stability of solutions to the Einstein-scalar field system in spherical symmetry
João L. Costa, Rodrigo Duarte, Filipe C. Mena
We investigate the asymptotic stability of solutions to the characteristic initial value problem for the Einstein (massless) scalar field system with a positive cosmological consta…
Dynamics of interacting monomial scalar field potentials and perfect fluids
Artur Alho, Vitor Bessa, Filipe C. Mena
Motivated by cosmological models of the early universe we analyse the dynamics of the Einstein equations with a minimally coupled scalar field with monomial potentials $V(ϕ)=\frac{…
Primordial magnetic fields in theories of gravity with non-minimal coupling between curvature and matter
Orfeu Bertolami, Maria Margarida Lima, Filipe C. Mena
The existence of magnetic fields in the universe is unmistakable. They are observed at all scales from stars to galaxy clusters. However, the origin of these fields remains enigmat…
Quasinormal modes and stability of boosted Reissner-Nordström AdS black holes
Rodrigo D. B. Fontana, Filipe C. Mena
We investigate the numerical stability of accelerated AdS black holes against linear scalar perturbations. In particular, we study the evolution of a probe non-minimally coupled sc…
