On a Schwarzschild-type defect wormhole
ZL Wang - arXiv preprint arXiv:2307.01678, 2023 - arxiv.org
We investigate a new type of Schwarzschild wormhole, which relies on a 3-dimensional
spacetime defect with degenerate metrics. This particular wormhole is a solution of the …

Shadows and rings of a de Sitter–Schwarzschild black hole
ZL Wang - The European Physical Journal Plus, 2023 - Springer
We study the optical appearance of a de Sitter–Schwarzschild black hole and its
distinguishability from a Schwarzschild black hole. By exploring various accretion models …
