We study collisions of boosted rotating black holes in $D=6$ and 7 spacetime dimensions with a non-zero impact parameter. We find that there exists an open set of initial conditions such that the intermediate state of the collision is a dumbbell-like horizon which is unstable to a Gregory-Laflamme-type instability. As is usually the case for similar unstable configurations, the evolution of such an instability leads to a pinch off of the horizon in finite asymptotic time, thus forming a naked singularity. Hence, this is the first fully genuine violation of Weak Cosmic Censorship conjecture in higher dimensional asymptotically flat spacetimes.
We study the evolution of black hole collisions and ultraspinning black hole instabilities in higher dimensions. These processes can be efficiently solved numerically in an effective theory in the limit of large number of dimensions D. We present evi
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 rings, we identify a new, elasti
Based on the new version of the gedanken experiment proposed by Sorce and Wald, we investigate the weak cosmic censorship conjecture (WCCC) for a Reissner-Nordstr{o}m-Anti-de Sitter (RN-AdS) black hole under the perturbation of extra matter fields. F
We investigate extremal electrically charged black holes in Einstein-Maxwell-dilaton theory with a cosmological constant inspired by string theory. These solutions are not static, and a timelike singularity eventually appears which is not surrounded
We study the model of Einstein-Maxwell theory minimally coupling to a massive charged self-interacting scalar field, parameterized by the quartic and hexic coupling, labelled by $lambda$ and $beta$, respectively. In the absence of scalar field, there
