Master functions and hybrid quantization of perturbed nonrotating black hole interiors
Michele Lenzi, Guillermo A. Mena Marugán, Andrés Mínguez-Sánchez
Master functions of black holes are fundamental tools in gravitational-wave physics and are typically derived within a Lagrangian framework. Starting from the Kantowski-Sachs geome…

Polar perturbations in Kantowski-Sachs spacetimes and hybrid quantum cosmology
Guillermo A. Mena Marugán, Andrés Mínguez-Sánchez
Increasing attention has been recently devoted to the study of Kantowski-Sachs spacetime as a way to explore the interior of a Schwarzschild black hole. In this work, we construct…
