Null Hypersurface Caustics, Closed Null Curves, and Super-Entropy
Sousuke Noda, Yen Chin Ong
Recently it was discovered that null hypersurfaces can develop caustics outside the event horizon of super-entropic Kerr-AdS black holes, in contrast to the usual Kerr-AdS case. In…
Hawking Evaporation of Black Holes in Massive Gravity
Meng-Shi Hou, Hao Xu, Yen Chin Ong
We study the Hawking evaporation of a class of black hole solutions in dRGT massive gravity, in which the graviton mass gives rise to an effective negative cosmological constant. W…
Event Horizon Wrinklification
Brett McInnes, Yen Chin Ong
The possible existence of stable black holes with entropies larger than the corresponding Schwarzschild black hole has been discussed extensively. The recently proposed "rough" bla…
Spacetime Singularities and Cosmic Censorship Conjecture: A Review with Some Thoughts
Yen Chin Ong
The singularity theorems of Hawking and Penrose tell us that singularities are common place in general relativity. Singularities not only occur at the beginning of the Universe at…
Regular Black Hole Interior Spacetime Supported by Three-Form Field
Mariam Bouhmadi-López, Che-Yu Chen, Xiao Yan Chew +2
In this paper, we show that a minimally coupled 3-form endowed with a proper potential can support a regular black hole interior. By choosing an appropriate form for the metric fun…
Schwinger Pair Production and the Extended Uncertainty Principle: Can Heuristic Derivations Be Trusted?
Yen Chin Ong
The rate of Schwinger pair production due to an external electric field can be derived heuristically from the uncertainty principle. In the presence of a cosmological constant, it…
Black Hole Evaporation in Hořava-Lifshitz Gravity
Hao Xu, Yen Chin Ong
Hořava-Lifshitz (HL) gravity was formulated in hope of solving the non-renormalization problem in Einstein gravity and the ghost problem in higher derivative gravity theories by vi…
The Interior Volume of Kerr-AdS Black Holes
Xiao Yan Chew, Yen Chin Ong
The interior volume of black holes as defined by Christodoulou and Rovelli exhibits many surprising features. For example, it increases with time, even under Hawking evaporation. F…
Particle spectrum of the Reissner-Nordström black hole
Michael R. R. Good, Yen Chin Ong
The Reissner-Nordström black hole - moving mirror correspondence is solved. The beta coefficients reveal that charge makes a black hole radiate fewer particles (neutral massless sc…
Thermodynamics of Shearing Massless Scalar Field Spacetimes is Inconsistent With the Weyl Curvature Hypothesis
Daniele Gregoris, Yen Chin Ong, Bin Wang
Our Universe has an arrow of time. In accordance with the second law of thermodynamics, entropy has been increasing ever since the Big Bang. The fact that matter is in thermal equi…
The Quantum Atmosphere of Reissner-Nordström Black Holes
Yen Chin Ong, Michael R. R. Good
Hawking radiation originates from a "quantum atmosphere" around black holes, not necessarily from the vicinity of the horizon. We examine and discuss the properties of quantum atmo…
