Hamiltonian formalism, master functions and Darboux transformations for perturbed (interiors and exteriors of) nonrotating black holes
Michele Lenzi, Guillermo A. Mena Marugán, Andrés Mínguez-Sánchez +1
Motivated by their relevance to the interior of nonrotating black holes, classical and quantum Kantowski-Sachs cosmologies have recently attracted increasing attention. This intere…
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…
Master variables and Darboux symmetry for axial perturbations of the exterior and interior of black hole spacetimes
Michele Lenzi, Guillermo A. Mena Marugán, Andrés Mínguez-Sánchez +1
Recent efforts have shown that Kantowski-Sachs spacetime provides a useful framework for analyzing perturbations inside a Schwarzschild black hole (BH). In these studies, the adopt…
Asymptotics and Universality in Black Holes: from the quasinormal Weyl's law to the binary merger waveform
José Luis Jaramillo, Lamis Al Sheikh, Jérémy Besson +7
Current state-of-the-art approaches to black hole (BH) dynamics, encompassing several effective approximation schemes, offer a remarkable control of the quantitative aspects of str…
Modified Black Hole Potentials and Their Korteweg-de Vries Integrals: Instabilities and Beyond
Michele Lenzi, Arnau Montava Agudo, Carlos F. Sopuerta
Black Hole (BH) Quasi-Normal Modes (QNMs) and Greybody Factors (GBFs) are key signatures of BH dynamics that are crucial for testing fundamental physics via gravitational waves. Re…
Korteweg-de Vries Integrals for Modified Black Hole Potentials: Instabilities and other Questions
Michele Lenzi, Arnau Montava Agudo, Carlos F. Sopuerta
Quasi-normal modes (QNMs) and greybody factors are some of the most characteristic features of the dynamics of black holes (BHs) and represent the basis for a number of fundamental…
