Highly damped Quasi-Normal Modes of a Loop Quantum Black Hole
Clara Montagnon
We compute asymptotic Quasi-Normal Mode (QNM) frequencies -- i.e. frequencies with a very large Imaginary part -- of a Loop Quantum Gravity inspired Black Hole. The deformations fr…
Algebraically special perturbations of the Kerr black hole: a metric formulation
Jibril Ben Achour, Clara Montagnon, Hugo Roussille
Perturbations of the Kerr black hole are notoriously difficult to describe in the metric formalism and are usually studied in terms of perturbations of the Weyl scalars. In this wo…
Test-Field vs Physical Quasi-Normal Modes in Scalar-Tensor Theories
Alexandre Arbey, Etera R. Livine, Clara Montagnon
In the context of the general effort to model black hole dynamics, and in particular their return-to-equilibrium through quasi-normal modes, it is crucial to understand how much te…
Scalar Quasi-Normal Modes of a Loop Quantum Black Hole
Etera R. Livine, Clara Montagnon, Naritaka Oshita +1
We compute the Quasi-Normal Mode (QNM) frequencies for scalar perturbations for modified Schwarzschild black holes in Loop Quantum Gravity. We study the singularity-free polymerize…
