Journal ArticleDOI
Shadow of a rotating traversable wormhole
TL;DR: In this article, the authors explore the shadow of rotating traversable wormholes within classical general relativity and compare the results with the case of the Kerr black hole, showing that the shadows for small angular momenta are nearly identical; however, with the increasing of the angular momentum, they start to deviate considerably.
Journal ArticleDOI
On the shadow of rotating traversable wormholes
TL;DR: The shadow of rotating traversable wormholes is revisited discussing the role of the wormhole throat in the shadow formation, and a couple of wormhole solutions are considered and the structure of their shadow images, and the intrinsic mechanisms for their formation are examined.
Journal ArticleDOI
On the shadow of rotating traversable wormholes
TL;DR: In this paper, the role of the wormhole throat in shadow formation is discussed and a couple of wormhole solutions are examined, in which the explicit mechanism for cusp formation can be uncovered.
Journal ArticleDOI
Possible imprints of cosmic strings in the shadows of galactic black holes
TL;DR: In this paper, the shadow cast by a Kerr black hole pierced by a cosmic string was examined and the dependence of the observable characteristics of the shadow on the deficit angle was explored.
Proceedings ArticleDOI
Cusp structure in shadows casted by rotating wormholes
TL;DR: In this article, the authors investigate the shadows of a certain class of rotating traversable wormholes and reveal their crucial role over the cusp formation in the shadows, and show that only some of the unstable spherical orbits possess specific impact parameters, which contribute to the shadow boundary.
