Bounds for Lyapunov exponent of circular light orbits in black holes

Emanuel Gallo, Thomas Mädler

Chaotic systems near black holes satisfy a universal bound, linking the Lyapunov coefficient associated with unstable orbits to surface gravity of the event h…

Apparent horizon tracking in supercritical solutions of the Einstein-scalar field equations in spherical symmetry in affine-null coordinates

Thomas Mädler, Olaf Baake, Hamideh Hosseini +1

Choptuik's critical phenomena in general relativity is revisited in the affine-null metric formulation of Einstein's equations for a massless scalar field in spherical symmetry. Nu…

Slowly rotating Kerr metric derived from the Einstein equations in affine-null coordinates

Thomas Mädler, Emanuel Gallo

Using a quasi-spherical approximation of an affine-null metric adapted to an asymptotic Bondi inertial frame, we present high order approximations of the metric functions in terms…

Shadows of rotating black holes in plasma environments with aberration effects

Gastón Briozzo, Emanuel Gallo, Thomas Mädler

The shadows of black holes encode significant information about the properties of black holes and the spacetime surrounding them. So far, the effects of dispersive media, such as p…

Spherically symmetric black holes and affine-null metric formulation of Einstein's equations

Emanuel Gallo, Carlos Kozameh, Thomas Mädler +2

The definition of well-behaved coordinate charts for black hole spacetimes can be tricky, as they can lead for example to either unphysical coordinate singularities in the metric (…

Editorial Note to: On the Newtonian Limit of Einstein's Theory of Gravitation (by Jürgen Ehlers)

Thomas Buchert, Thomas Mädler

We give an overview of literature related to Jürgen Ehlers' pioneering 1981 paper on Frame theory--a theoretical framework for the unification of General Relativity and the equatio…
