Description
The extension of General Relativity by including quadratic curvature invariants in the Einstein-Hilbert action is one of the most extensively studied alternative gravity theories today. In this contribution, we employ the quadratic gravity field equations, formulated using the Newman-Penrose formalism, to analyse extensions of the Kerr black hole spacetime going beyond GR. We derive constraints on the linear gravitational perturbations of this background. Here, we summarise the key concepts leading to the general form of these constraints, while detailed explicit examples will be presented in a separate contribution.
