Black holes in a box: towards the numerical evolution of black holes in AdS

Witek, Helvi, Cardoso, Vitor, Herdeiro, Carlos et al.

Understand

The evolution of black holes in "confining boxes" is interesting for a number of reasons, particularly because it mimics the global structure of Anti-de Sitter geometries.

  • These are non-globally hyperbolic space-times and the Cauchy problem may only be well defined if the initial data is supplemented by boundary conditions at the time-like conformal boundary.
  • Here, we explore the active role that boundary conditions play in the evolution of a bulk black hole system, by imprisoning a black hole binary in a box with mirror-like boundary conditions.
  • We are able to follow the post-merger dynamics for up to two reflections off the boundary of the gravitational radiation produced in the merger.
