  • Nielsen, Alex B.; Shoom, Andrey A. (Bristol : Institute of Physics Publishing, 2018)
    Certain dynamical black hole solutions can be mapped to static spacetimes by conformal metric transformations. This mapping provides a physical link between the conformal Killing horizon of the dynamical black hole and the ...
  • Pook-Kolb, Daniel Klaus Ortwin (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
    Marginally outer trapped surfaces (MOTSs) are the main tool in numerical relativity to infer properties of black holes in simulations of highly dynamical systems. On the one hand, the present work extends previous numerical ...

  • Fennen, Michael; Giulini, Domenico (Bristol : Institute of Physics Publishing (IOP), 2020)
    In this paper we propose to use Lie sphere geometry as a new tool to systematically construct time-symmetric initial data for a wide variety of generalised black-hole configurations in lattice cosmology. These configurations ...
