Applications of Numerical Relativity Beyond Astrophysics
(Department of Applied Mathematics and Theoretical Physics, University of CambridgeUniversity of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsEmmanuel College, 2017)Numerical relativity has proven to be a successful and robust tool for non-perturbative studies of gravitational phenomena in the highly dynamical and/or non-linear regime. Perhaps the most prominent achievement in the ...

Dimensional reduction in numerical relativity: Modified cartoon formalism and regularization
(World Scientific Publishing CompanyInternational Journal of Modern Physics D, 2016-06-01)We present in detail the Einstein equations in the Baumgarte–Shapiro–Shibata–Nakamura formulation for the case of D-dimensional spacetimes with SO(D−d)isometry based on a method originally introduced in Ref. 1. Regularized ...

End point of Black Ring Instabilities and the Weak Cosmic Censorship Conjecture
(American Physical SocietyPhysical Review Letters, 2016-02-18)We produce the first concrete evidence that violation of the weak cosmic censorship conjecture can occur in asymptotically flat spaces of five dimensions by numerically evolving perturbed black rings. For certain thin ...

End Point of the Ultraspinning Instability and Violation of Cosmic Censorship
(American Physical SocietyAmerican Physical SocietyPhysical Review Letters, 2017-04-14)We determine the end point of the axisymmetric ultraspinning instability of asymptotically flat Myers-Perry black holes in D = 6 spacetime dimensions. In the nonlinear regime, this instability gives rise to a sequence of ...
