Black Shell Thermodynamics
Ulf Danielsson, Vyshnav Mohan, Larus Thorlacius
Black shells have been proposed as black hole mimickers, i.e. horizonless ultra-compact objects that replace black holes. In this paper, we assume the existence of black shells and…

Black hole mimickers: from theory to observation
Cosimo Bambi, Ramy Brustein, Vitor Cardoso +16
The black hole paradigm, while remarkably successful, raises fundamental questions-both classical and quantum-about the nature of spacetime, horizons, and singularities. Black hole…

Exploring Black Hole Mimickers: Electromagnetic and Gravitational Signatures of AdS Black Shells
Suvendu Giri, Ulf Danielsson, Luis Lehner +1
We study electromagnetic and gravitational properties of AdS black shells (also referred to as AdS black bubbles) -- a class of quantum gravity motivated black hole mimickers, that…
