Vishveshwara's waveform revisited: insights from a Keldysh quasinormal mode expansion
Jérémy Besson, José Luis Jaramillo
We revisit Vishveshwara's linear scattering on a Schwarzschild black hole to study the evolution of quasinormal mode activation along the full time-domain waveform. Specifically, b…
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…
Transients in black hole perturbation theory
Jérémy Besson, Javier Carballo, Christiana Pantelidou +1
Black hole quasinormal modes arise as eigenmodes of a non-normal Hamiltonian and consequently they do not obey orthogonality relations with respect to commonly used inner products,…
Quasi-normal mode expansions of black hole perturbations: a hyperboloidal Keldysh's approach
Jérémy Besson, José Luis Jaramillo
We study quasinormal mode expansions by adopting a Keldysh scheme for the spectral construction of asymptotic resonant expansions. Quasinormal modes are first cast in terms of a no…
