DOI: 10.1007/s10773-024-05644-5
Abstract: In this work, the trajectories of particles around a black bounce spacetime are considered, with the Simpson-Visser model serving as an example. Trajectories for massless and massive particles are obtained through the study of null… read more here.

DOI: 10.1103/physrevd.104.064022
Abstract: We investigate gravitational lensing by a primary photon sphere which is formed by unstable circular light orbits, and by a secondary photon sphere on a wormhole throat in a black-bounce spacetime which is suggested in… read more here.

Abstract: We obtain one family of dynamic solutions in the Einstein-Maxwell-scalar(EMS) theory. Our solutions could describe the evolving charged black(white) hole or wormhole and its transition, including the case of black bounce/wormhole transition. We compare different… read more here.

DOI: 10.3390/universe11070221
Abstract: The central singularity present in black hole (BH) spacetimes arising in the general theory of relativity (GR) can be avoided by using various methods. In the present work we have investigated the gravitational effect of… read more here.
