Cosmic Censorship and the Evolution of d-Dimensional Charged Evaporating Black Holes
Hao Xu, Yen Chin Ong, Man-Hong Yung
The cosmic censorship conjecture essentially states that naked singularities should not form from generic initial conditions. Since black hole parameters can change their values un…
The Horizon of the McVittie Black Hole: On the Role of the Cosmic Fluid Modeling
Daniele Gregoris, Yen Chin Ong, Bin Wang
In this paper, we investigate the existence and time evolution of the cosmological and event horizons in a McVittie universe whose expansion is driven by the Redlich-Kwong, (Modifi…
The Attractor of Evaporating Reissner-Nordström Black Holes
Yen Chin Ong
Hiscock and Weems showed that there is an attractor behavior in the evolution of asymptotically flat Reissner-Nordström black hole under Hawking evaporation. If the initial charge-…
The Charge of Electron, Weak Gravity Conjecture and Black Hole Evolution
Yen Chin Ong
The charge of an electron is vastly larger than its mass. We found that black hole evolution under Hawking evaporation is very sensitive to the value of electron charge. If the ele…
Charged Particle Production Rate from Cosmic Censorship in Dilaton Black Hole Spacetimes
Yen Chin Ong, Yuan Yao
Hiscock and Weems showed that under Hawking evaporation, an isolated asymptotically flat Reissner-Nordstrom (RN) black hole evolves in a surprising manner: if it starts with a rela…
No Violation of the Second Law in Extended Black Hole Thermodynamics
Shi-Qian Hu, Yen Chin Ong, Don N. Page
Recently a number of papers have claimed that the horizon area - and thus the entropy - of near extremal black holes in anti-de Sitter spacetimes can be reduced by dropping particl…
Holographic Principle and the Second Law in Stephani Cosmology Revisited
Daniele Gregoris, Yen Chin Ong, Bin Wang
We show in a model-independent way that the inhomogeneous cosmological class II Stephani model fulfills both the the cosmological holographic principle, and that the entropy is inc…
Curvature Invariants and Lower Dimensional Black Hole Horizons
Daniele Gregoris, Yen Chin Ong, Bin Wang
It is known that the event horizon of a black hole can often be identified from the zeroes of some curvature invariants. The situation in lower dimensions has not been thoroughly c…
General Black Hole Solutions in (2+1)-dimensions with a Scalar Field Non-Minimally Coupled to Gravity
Zi-Yu Tang, Yen Chin Ong, Bin Wang +1
We discuss black hole solutions in (2+1)-dimensions with a scalar field non-minimally coupled to Einstein's gravity in the presence of a cosmological constant and a self-interactin…
