Novel shadows from the asymmetric thin-shell wormhole
Xiaobao Wang, Peng-Cheng Li, Cheng-Yong Zhang +1
For dark compact objects such as black holes or wormholes, the shadow size has long been thought to be determined by the unstable photon sphere (region). However, by considering th…
Traversable Thin-shell Wormhole in the 4D Einstein-Gauss-Bonnet Theory
Peng Liu, Chao Niu, Wei-Liang Qian +2
This work investigates the spherically symmetric thin-shell wormhole solutions in four-dimensional Einstein-Gauss-Bonnet theory and explores their stabilities under radial, linear…
Critical phenomena in gravitational collapse of Husain-Martinez-Nunez scalar field
Xiaobao Wang, Xiaoning Wu, Sijie Gao
We construct analytical models to study the critical phenomena in gravitational collapse of the Husain-Martinez-Nunez massless scalar field. We first use the cut-and-paste techniqu…
Construction of Regular Black Holes in General Relativity
Zhong-Ying Fan, Xiaobao Wang
We present a general procedure for constructing exact black hole solutions with electric or magnetic charges in General Relativity coupled to a nonlinear electrodynamics. We obtain…
A static spherically symmetric thin shell wormhole colliding with a spherical thin shell
Sijie Gao, Xiaobao Wang
We consider a static spherically symmetric thin shell wormhole collides with another thin shell consisting of ordinary matter. By employing the geometrical constraint, which leads…
Thin shell model revisited
Sijie Gao, Xiaobao Wang
We reconsider some fundamental problems of the thin shell model. First, we point out that the "cut and paste" construction does not guarantee a well-defined manifold because there…
