Black hole mimicker hiding in the shadow: Optical properties of the metric
Can the observation of the “shadow” allow us to distinguish a black hole from a more exotic
compact object? We study the motion of photons in a class of vacuum static axially …

Modeling black hole evaporative mass evolution via radiation from moving mirrors
We investigate the evaporation of an uncharged and nonrotating black hole in vacuum by
taking into account the effects given by the shrinking of the horizon area. These include the …

Stationary rotating and axially symmetric dust systems as peculiar General Relativistic objects
ML Ruggiero - Journal of Cosmology and Astroparticle Physics, 2024 - iopscience.iop.org
We study an exact solution of Einstein's equations describing a self-gravitating system,
made of dust, distributed with axial symmetry and in stationary rotation, and we prove that …

Matching van Stockum dust to Papapetrou vacuum
M Marvan - Journal of Geometry and Physics, 2023 - Elsevier
Addressing a long-standing problem, we show that every van Stockum dust can be matched
to a 1-parametric family of non-static Papapetrou vacuum metrics, and the converse. The …
