Hawking radiation and graybody factor of slightly deformed Schwarzschild black holes
Asier Alonso-Bardaji, David Brizuela, Marc Schneider
We analyze the radiative properties of a general class of static and spherically symmetric black holes described by three independent shape functions, that encompass a broad family…

Radial quantization of the Schwarzschild geometry: relational observables, evaporation, and remnant state
David Brizuela, Leonardo Chataignier, Mikel López-Escondrillas
We consider the canonical quantization of the Schwarzschild geometry in a minisuperspace description based on a foliation with leaves labeled by the radial variable. This formulati…
