There is a growing interest in investigating Kantowski-Sachs cosmologies owing to their relation with the interior of nonrotating, uncharged black holes. In particular, we recently developed a Hamiltonian formulation of axial perturbations for a massless scalar field minimally coupled to these cosmologies, describing physical perturbations by gauge invariants. Adopting this formulation, we...
A recent covariant formulation, which includes non-perturbative effects from loop quantum gravity (LQG) as self-consistent effective models, has revealed the possibility of non-singular black hole solutions. The new framework makes it possible to couple scalar matter to such LQG black holes and derive Hawking radiation in the presence of quantum space-time effects while respecting general...
Black holes serve as key testing grounds for quantum gravity due to their singular nature and have been extensively studied in various quantum gravity approaches. In this talk, I apply the Henneaux-Teitelboim formulation of unimodular gravity to the symmetry-reduced Schwarzschild-(Anti-)de Sitter model. We perform a canonical quantization, leading to a Wheeler-DeWitt equation that takes the...
