Coordinates are messy -- not only in General Relativity
Carla Cederbaum, Melanie Graf
The coordinate freedom of General Relativity makes it challenging to find mathematically rigorous and physically sound definitions for physical quantities such as the center of mas…
Exact Parallel Waves in General Relativity
Cian Roche, Amir Babak Aazami, Carla Cederbaum
We conduct a review of the basic definitions and the principal results in the study of wavelike spacetimes, that is spacetimes whose metric models massless radiation moving at the…
Level sets of the lapse function in static GR
Carla Cederbaum
We present a novel physical interpretation of the level sets of the (canonical) lapse function in static isolated general relativistic space-times. Our interpretation uses a notion…
The Newtonian Limit of Geometrostatics
Carla Cederbaum
This thesis discusses the Newtonian limit of General Relativity for static isolated systems with compactly supported matter. We call these systems "geometrostatic" to underline the…
Universal properties of distorted Kerr-Newman black holes
Marcus Ansorg, Jörg Hennig, Carla Cederbaum
We discuss universal properties of axisymmetric and stationary configurations consisting of a central black hole and surrounding matter in Einstein-Maxwell theory. In particular, w…
A universal inequality for axisymmetric and stationary black holes with surrounding matter in the Einstein-Maxwell theory
Jörg Hennig, Carla Cederbaum, Marcus Ansorg
We prove that in Einstein-Maxwell theory the inequality holds for any sub-extremal axisymmetric and stationary black hole with arbitrary surrounding matte…
