Quasinormal-mode analysis of a massive scalar field in a Schwarzschild background via the spectral method
Davide Batic, Anna Chrysostomou, Alan S. Cornell +1
We study the massive scalar quasinormal-mode spectral problem on a Schwarzschild background using an extended Chebyshev spectral method. The massive dispersion relation has a two-s…
Gravitationally-decoupled hairy black holes: probing geometric, optical, and quasinormal mode signatures
Paul Allen M. Gonzales, Anna Chrysostomou, Alan S. Cornell +1
Gravitational-decoupling provides a systematic framework for constructing black hole geometries from known (seed) solutions (such as the Schwarzschild), whose exterior properties c…
Adiabatic Deformations of Black Hole Moduli: II. The Magnetic GHS Family
Karim Benakli, Anna Chrysostomou
We study the leading adiabatic response of magnetic GHS black holes in massless Einstein-Maxwell-dilaton theory to a prescribed exterior modulus varying slowly in advanced time. In…
Adiabatic Deformations of Black Hole Moduli: I. Canonical Slices and Fredholm Solvability
Karim Benakli, Anna Chrysostomou
The leading adiabatic response of a static black hole to a slowly evolving asymptotic modulus separates into a geometric problem and a functional-analytic one: the former identifie…
The Fate of Black Hole-Induced Moduli Excursions in the Presence of Scalar Potentials
Karim Benakli, Anna Chrysostomou
Large charged black holes can create macroscopic, locally weakly curved regions in which moduli take values different from their asymptotic values. We study how robust this mechani…
