Ampl2Einstein: Scattering Amplitudes for Gravitational Wave Theory

The observation of gravitational waves from a binary black hole merger in 2016 marked the beginning of an exciting new era for astronomy. More findings about black holes and neutron stars are expected to be revealed in the future. To make use of the new observations, theoretical physicists will need to develop more accurate numerical methods and better mathematical descriptions of gravitational signals. Ampl2Einstein will build on advances in quantum scattering amplitudes that are used to calculate collisions of elementary particles. Furthermore, use of the Yang–Mills theory will play a key role in making this route simpler than direct classical calculations. The project's advances will allow astronomers to detect weaker gravitational signals and resolve long-standing puzzles regarding the internal structure of neutron stars.
