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.

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.
