The Topical Collection “Hyperboloidal Foliations in the Era of Gravitational-Wave Astronomy: From Mathematical Relativity to Astrophysics” grew out of interactions at the workshop “Infinity on a Gridshell” in Copenhagen in 2023. Contributors were invited to expand their presentations into full articles, or submit new research motivated by the discussions. The result is a snapshot of a field in rapid development: papers that solidify the linear theory on fixed backgrounds, push numerical techniques to spectral accuracy at null infinity, clarify the role of conserved charges and regularity at scri+, and take further steps toward fully nonlinear hyperboloidal evolutions without symmetry.
