Amplification of new physics in the quasinormal mode spectrum of highly-rotating black holes
Pablo A. Cano, Marina David, Guido van der Velde
We show that perturbatively-small higher-derivative corrections to the Einstein-Hilbert action can lead to order-one modifications of the quasinormal mode spectrum of near-extremal…

Eikonal quasinormal modes of highly-spinning black holes in higher-curvature gravity: a window into extremality
Pablo A. Cano, Marina David, Guido van der Velde
We carry out the first computation of gravitational quasinormal modes of black holes with arbitrary rotation in a theory with higher-derivative corrections. Our analysis focuses on…

Microstates of AdS black holes with hypermultiplets
Marina David, Annelien Vekemans
We construct supersymmetric rotating AdS black holes in 5d gauged supergravity coupled to two vector multiplets and a universal hypermultiplet, and verify their…
