Kerr-Degenerate Shadows and Distinct Strong-Deflection Lensing in Rotating Hayward-like and Bardeen-like Geometries
Chen-Hung Hsiao, Limei Yuan, Yidun Wan
We study and compare rotating Hayward-like and Bardeen-like geometries within a common Kerr-like axisymmetric ansatz, with the models distinguished by their areal-radius functions…

Gravitational Lensing Signatures of Hayward-like Black Holes
Chen-Hung Hsiao, Limei Yuan, Yidun Wan
We examine the gravitational lensing signatures of a Hayward-like regular black hole and its potential observational distinction from a Schwarzschild black hole. In the weak-field…

Distinguish Bardeen-like black holes by Gravitational lensing
Limei Yuan, Chen-Hung Hsiao, Yidun Wan
We study Bardeen-like regular black holes without Cauchy horizons via gravitational lensing. In the weak field, the deflection angle receives a positive -dependent correction…
