Backreactions from loading the stable photon sphere in Weyl conformal gravity
Reinosuke Kusano, Keith Horne, Friedrich Koenig +1
We investigate the accumulation of null matter at the stable photon sphere in the Mannheim-Kazanas metric, the analogue to the Schwarzschild solution in Weyl's conformal theory of…

Hyperboloidal Method for Quasinormal Modes of Non-Relativistic Operators
Christopher Burgess, Friedrich Koenig
The recently reported compactified hyperboloidal method has found wide use in the numerical computation of quasinormal modes, with implications for fields as diverse as gravitation…
