Isospectrality in Effective Field Theory Extensions of General Relativity
Pablo A. Cano, Marina David
Two universal predictions of general relativity are the propagation of gravitational waves of large momentum along null geodesics and the isospectrality of quasinormal modes in man…

Teukolsky equation for near-extremal black holes beyond general relativity: near-horizon analysis
Pablo A. Cano, Marina David
We study gravitational perturbations on the near-horizon region of extremal and near-extremal rotating black holes in a general higher-derivative extension of Einstein gravity. We…

Near-horizon geometries and black hole thermodynamics in higher-derivative AdS supergravity
Pablo A. Cano, Marina David
Higher-derivative corrections in the AdS/CFT correspondence allow us to capture finer details of the dual CFT and to explore the holographic dictionary beyond the infinite N and st…
