Abstract: We prove two results which are relevant for constructing marginally outer trapped tubes (MOTTs) in de Sitter spacetime. The first one (Theorem 1) holds more generally, namely for spacetimes satisfying the null convergence condition and… read more here.

Abstract: We study the open and closed axisymmetric marginally outer trapped surfaces contained in leaves of constant Painleve-Gullstrand time for Schwarzschild spacetimes. We identify a family of closed MOTS in the black hole interior characterized by… read more here.
