Hamiltonian formalism, master functions and Darboux transformations for perturbed (interiors and exteriors of) nonrotating black holes
Michele Lenzi, Guillermo A. Mena Marugán, Andrés MÃnguez-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 variables and Darboux symmetry for axial perturbations of the exterior and interior of black hole spacetimes
Michele Lenzi, Guillermo A. Mena Marugán, Andrés MÃnguez-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…
Master functions and hybrid quantization of perturbed nonrotating black hole interiors
Michele Lenzi, Guillermo A. Mena Marugán, Andrés MÃnguez-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…
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…
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…
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…
