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…
Gravitational-wave tails and memory effect for mergers in astrophysical environments
Qassim Alnasheet, Vitor Cardoso, Francisco Duque +1
Gravitational waves from the coalescence of compact objects carry information about their dynamics and the spacetime in regions where they are evolving. In particular, late-time ta…
Limiting geometry and spectral instability in Schwarzschild--de Sitter spacetimes
Yi Zhou, Rodrigo Panosso Macedo
We revisit the quasinormal mode (QNM) problem in Schwarzschild--de Sitter spacetimes providing a unified infrastructure tailored for studying limiting configurations. Geometrically…
Pseudospectrum of rotating analog black holes
Lucas Tobias de Paula, Pedro Henrique Croti Siqueira, Rodrigo Panosso Macedo +1
Analyzing the stability of quasinormal modes (QNM) is essential for understanding black hole dynamics, particularly in the context of gravitational wave emissions and black hole sp…
Black hole spectral instabilities in the laboratory: Shallow water analogue
Mateus Malato Corrêa, Caio F. B. Macedo, Rodrigo Panosso Macedo +1
Small deviations in the spacetime around black holes can lead to instabilities in the underlying quasinormal mode spectrum, potentially altering the hierarchy of its overtones. A p…
Probing the Unstable Spectrum of Schwarzschild-like Black Holes
Pedro Henrique Croti Siqueira, Lucas Tobias de Paula, Rodrigo Panosso Macedo +1
We investigate the pseudospectrum of a Schwarzschild-like spacetime within the framework of black hole perturbation theory to analyze a counterintuitive assertion regarding the ins…
