Purely Electric, Magnetic, and Dyonic Black Holes in Einstein-Euler-Heisenberg Theory
Haoyuan Luo, Nan Cao, Xiao Yan Chew +3
We investigate static, spherically symmetric charged black holes in Einstein gravity coupled to Euler--Heisenberg (EH) nonlinear electrodynamics, including purely electric, purely…
The Interior of the Scalar Hairy Black Hole with Inverted Higgs Potential
Xiao Yan Chew, Kok-Geng Lim, Dong-han Yeom
We investigate the interior structure of asymptotically flat hairy black holes (HBHs) arising in the Einstein-Klein-Gordon theory with nonpositive-definite scalar potentials, where…
Violation of weak cosmic censorship by the Oppenheimer-Snyder collapse
Il Gyeong Choi, Dong-han Yeom
We consider the possibility that the weak cosmic censorship conjecture can be violated using the Oppenheimer-Snyder collapse model with a perfect fluid star interior. Metric models…
Dynamics of Bronnikov-Ellis wormhole with double-null simulation
Anyuan Xu, Xiao Yan Chew, Dong-han Yeom
We investigate the dynamical collapse of Bronnikov-Ellis (BE) wormhole using the double-null formalism, where its throat is characterized by the coincidence of two curves $r_{,u} =…
