Bilinear products and the orthogonality of quasinormal modes on hyperboloidal foliations
Marica Minucci, Rodrigo Panosso Macedo, Christiana Pantelidou +1
We explore the properties of bilinear products for black-hole quasinormal modes (QNMs) formulated on hyperboloidal foliations. We find that, although QNM solutions are smooth and f…

The Confluent Heun functions in Black Hole Perturbation Theory: a spacetime interpretation
Marica Minucci, Rodrigo Panosso Macedo
This work provides a spacetime interpretation of the confluent Heun functions within black hole perturbation theory (BHPT) and explores their relationship to the hyperboloidal fram…
