Abstract
This school is designed for students and postdocs eager to explore cutting-edge developments in gravity in asymptotically flat spacetimes. The program will explore the rich interplay between asymptotic symmetries in General Relativity, scattering amplitudes, and gravitational wave observables. Participants will also be introduced to twistor theory and to the emerging fields of celestial and Carrollian holography. Each topic will be presented through four to five hours of lectures by world-renowned experts, offering a comprehensive introduction for young researchers in the field.

Topics
Amplitudes, waveforms and memory effects — Carlo Heissenberg (IPhT Saclay)
Asymptotic symmetries — Simone Speziale (CNRS & Marseille University)
Carroll physics for holography — Yannick Herfray (IDP Tours)
Celestial holography — Tim Adamo (University of Edinburgh)
Twistor approach to asymptotic symmetries and flat holography — Tim Adamo (University of Edinburgh)
