Topical Collection-Hyperboloidal Foliations in the Era of Gravitational-Wave Astronomy: From Mathematical Relativity to Astrophysics

Abstract: Editorial introducing the GRG Topical Collection "Hyperboloidal foliations in the era of gravitational-wave astronomy," on hyperboloidal slices. The collection includes contributions spanning black-hole perturbations, asymptotic geometry, initial-data, and high-accuracy numerical methods relevant to gravitational-wave modeling. The collection grew out of the 2023 "Infinity on a Gridshell" workshop in Copenhagen.
