TL;DR
This paper presents numerical evidence for the existence of Skyrmion and Skyrme-Black hole solutions in de Sitter spacetime, highlighting their properties and differences from flat spacetime configurations.
Contribution
It introduces new numerical solutions of Einstein-Skyrme equations with positive cosmological constant, expanding understanding of these configurations in de Sitter space.
Findings
Solutions approach de Sitter spacetime asymptotically
Mass evaluated at infinity is infinite in de Sitter space
De Sitter black holes with Skyrmions have two horizons
Abstract
Numerical arguments are presented for the existence of regular and black hole solutions of the Einstein-Skyrme equations with a positive cosmological constant. These classical configurations approach asymptotically the de Sitter spacetime. The main properties of the solutions and the differences with respect to the asymptotically flat ones are discussed. It particular our results suggest that, for a positive cosmological constant, the mass evaluated as timelike infinity in infinite. Special emphasis is set to De Sitter black holes Skyrmions which display two horizons.
