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.
