The time evolution of marginally trapped surfaces
Lars Andersson, Marc Mars, Jan Metzger +1
In previous work we have shown the existence of a dynamical horizon or marginally trapped tube (MOTT) containing a given strictly stable marginally outer trapped surface (MOTS). In…
Topological censorship for Kaluza-Klein space-times
Piotr T. Chruściel, Gregory J. Galloway, Didier Solis
The standard topological censorship theorems require asymptotic hypotheses which are too restrictive for several situations of interest. In this paper we prove a version of topolog…
Some remarks on the size of bodies and black holes
Gregory J. Galloway, Niall O'Murchadha
We consider the application of stable marginally outer trapped surfaces to problems concerning the size of material bodies and the area of black holes. The results presented extend…
The area of horizons and the trapped region
Lars Andersson, Jan Metzger
This paper considers some fundamental questions concerning marginally trapped surfaces, or apparent horizons, in Cauchy data sets for the Einstein equation. An area estimate for ou…
Uniqueness of de Sitter space
Gregory J. Galloway, Didier A. Solis
All inextendible null geodesics in four dimensional de Sitter space dS^4 are complete and globally achronal. This achronality is related to the fact that all observer horizons in d…
Some uniqueness results for dynamical horizons
Abhay Ashtekar, Gregory J. Galloway
We first show that the intrinsic, geometrical structure of a dynamical horizon is unique. A number of physically interesting constraints are then established on the location of tra…
