Shadow of the Scalar Hairy Black Hole with Inverted Higgs Potential
Kok-Geng Lim, Xiao Yan Chew
We study the imaging of a hairy black hole (HBH) in the Einstein-Klein-Gordon theory, where Einstein gravity is minimally coupled to a scalar potential with …
Gravitating Scalarons with Inverted Higgs Potential
Xiao Yan Chew, Kok-Geng Lim
Previously, a class of regular and asymptotically flat gravitating scalar solitons (scalarons) has been constructed in the Einstein--Klein--Gordon (EKG) theory by adopting a phanto…
Scalar Hairy Black Holes with Inverted Mexican Hat Potential
Xiao Yan Chew, Kok-Geng Lim
We numerically construct the asymptotically flat solutions of hairy black holes supported by a symmetric inverted Mexican hat potential with a local minimum and two degenerate glob…
Non-Abelian Wormholes Threaded by a Yang-Mills-Higgs Field beyond the BPS Limit
Xiao Yan Chew, Kok-Geng Lim
We construct numerically the symmetric non-Abelian wormholes which are supported by a phantom field in the Einstein-Yang-Mills-Higgs theory beyond Bogomol'nyi-Prasad-Sommerfield (B…
Non--Abelian Wormholes Threaded by Yang--Mills--Higgs Field in the BPS Limit
Xiao Yan Chew, Kok-Geng Lim
In the Bogomol'nyi-Prasad-Sommerfield (BPS) limit of Einstein-Yang-Mills-Higgs theory, we construct numerically a non-Abelian wormhole supported by a phantom field. The probe limit…
