Kerr–Newman black holes can be generically overspun
Düztaş, Koray (Springer Nature, 2019-04-08)We construct thought experiments involving the perturbations of Kerr-Newman black holes by neutral test fields to evaluate the validity of the weak form of the cosmic censorship conjecture. We first show that neglecting ... -
Overcharging dilaton black holes in (2+1) dimensions to extremality and beyond
Düztaş, Koray; Jamil, M. (World Scientific Publishing Co Pte Lt, 2020-12)We test whether static charged dilaton black holes in (2 + 1) dimensions can be turned into naked singularities by sending in test particles from infinity. We derive that overcharging is possible and generic for both ... -
Overspinning Kerr-MOG black holes by test fields and the third law of black hole dynamics
Düztaş, Koray (Springer Nature, 2020-01-11)We evaluate the validity of the weak form of the cosmic censorship conjecture and the third law of black hole dynamics for Kerr-MOG black holes interacting with test scalar fields. Ignoring backreaction effects, we first ... -
String analog of Reissner–Nordström black holes cannot be overcharged
Düztaş, Koray; Jamil, M. (World Scientific Publishing Co Pte Lt, 2019-09-28)In this work, we attempt to overcharge extremal and nearly extremal charged black holes in string theory, known as the Garfinkle-Horowitz-Strominger solution. We first show that extremal black holes cannot be overcharged ... -
Testing cosmic censorship conjecture for extremal and near-extremal (2 + 1)-dimensional MTZ black holes
Düztaş, Koray; Jamil, M.; Shaymatov, S.; Ahmedov, B. (IOP Publishing, 2020-09-03)We test the validity of the weak cosmic censorship conjecture for the (2 + 1)-dimensional charged anti-de Sitter black hole solution, which was derived by Martinezet al(MTZ). We first construct a thought experiment by ...
