Light trajectories and optical appearances in asymptotically Anti-de Sitter-Schwarzschild and black string space-times
G. Alencar, Arthur Lima, Diego Rubiera-Garcia +1
The Event Horizon Telescope (EHT) imaging of the central objects in the M87 and Milky Way galaxies provide compelling evidence that these objects are consistent with (Kerr) black h…
Tidal forces around the Letelier-Alencar cloud of strings black hole
Marcos V. de S. Silva, T. M. Crispim, R. R. Landim +2
In this work, we investigate relativistic tidal forces around a black hole sourced by a cloud of strings, described by the generalized Letelier-Alencar solution. We first review th…
New light rings from multiple critical curves as observational signatures of black hole mimickers
Gonzalo J. Olmo, Diego Rubiera-Garcia, Diego Sáez-Chillón Gómez
We argue that the appearance of additional light rings in a shadow observation - beyond the infinite sequence of exponentially demagnified self-similar rings foreseen in the Kerr s…
