The linearised conformal Einstein field equations around a Petrov-type~D spacetime: the conformal Teukolsky equation
Edgar Gasperin, Rodrigo Panosso Macedo, Justin Feng
While the Teukolsky equation plays a central role in traditional treatments of perturbations of algebraically special spacetimes, its relation to Friedrich's conformal Einstein fie…

Quasinormal modes in Kerr spacetime as a 2D Eigenvalue problem
Jamil Assaad, Rodrigo Panosso Macedo
We revisit the computation of quasinormal modes (QNMs) of the Kerr black hole using a numerical approach exploiting a representation of the Teukolsky equation as a elliptic pa…
