Higher-curvature theories of gravity are extensions of General Relativity (GR) that arise in effective descriptions of quantum gravity theories, such as String Theory. While at low energies the behaviour of the gravitational field in higher-curvature gravities is almost indistinguishable from the one predicted by GR, the differences can be dramatic in extreme gravity scenarios, such as in the case of black holes (BHs). It is therefore an exciting task to study how black hole geometries are… Expand
