Proof of the weak cosmic censorship conjecture for several extremal black holes
Jéssica Gonçalves,José Natário +1 more
TL;DR: In this paper, it was shown explicitly that test fields satisfying the null energy condition at the event horizon cannot violate the weak cosmic censorship conjecture for extremal black holes, and that the hypotheses for the general theorem in [7] are satisfied.
Journal Article
Gravitational Collapse to Toroidal and Higher Genus asymptotically AdS Black Holes
TL;DR: In this paper, the authors match collapsing inhomogeneous as well as spatially homogeneous but anisotropic spacetimes to vacuum static exteriors with a negative cosmological constant and planar or hyperbolic symmetry.
Journal ArticleDOI
The problem of a self-gravitating scalar field with positive cosmological constant
TL;DR: In this paper, the Einstein-scalar field system with positive cosmological constant and spherically symmetric characteristic initial data given on a truncated null cone is studied.
Journal ArticleDOI
Warp Drive With Zero Expansion
TL;DR: In this article, it is shown that this expansion/contraction is but a marginal consequence of the choice made by Alcubierre, and explicitly constructed a similar spacetime where no contraction/expansion occurs.
Journal ArticleDOI
Spherical linear waves in de Sitter spacetime
TL;DR: In this paper, Christodoulou's framework was applied to the linear wave equation in de Sitter spacetime, as a first step towards the Einstein-scalar field equations with positive cosmological constant.
