Image of a wormhole with an arbitrary throat profile
Valeria A. Ishkaeva, Sergey V. Sushkov
We investigate the observable signatures -- the shadow, the throat silhouette, and the image of a thin accretion disk -- for a family of static, spherically symmetric wormholes wit…

Gravitational lensing by Lema\^ıtre-Tolman-Bondi wormholes in a Friedmann universe
Kirill A. Bronnikov, Valeria A. Ishkaeva, Sergey V. Sushkov
The Lema\^ıtre-Tolman-Bondi (LTB) solution to the Einstein equations describes the dynamics of a self-gravitating spherically symmetric dust cloud with an arbitrary density profile…

Image of an accreting general Ellis-Bronnikov wormhole
Valeria A. Ishkaeva, Sergey V. Sushkov
Gravitational lensing properties of supermassive astrophysical objects, such as black holes and wormholes, provide the realistic way for their discovering and investigating. Variou…
