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…
A Solar-System Window for Hidden Stellar Companions
Karim Benakli
Could the closest stellar or substellar object to the Sun be not an ordinary star at parsec distance, but a hidden-brane companion at hundreds or thousands of astronomical units? W…
Charged massive spin 2 and 3/2 propagation in a constant electromagnetic background
Karim Benakli, Wenqi Ke, Bruno Le Floch
We present two methods for deriving the equations of motion for charged massive spin-3/2 particles. The first approach involves utilizing the Euler-Lagrange equations derived from…
