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…
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…
