Amplitudes for Astrophysicists: Known Knowns

Understand

The use of quantum field theory to understand astrophysical phenomena is not new.

• However, for the most part, the methods used are those that have been developed decades ago.
• The intervening years have seen some remarkable developments in computational quantum field theoretic tools.
• In particle physics, this technology has facilitated calculations that, even ten years ago would have seemed laughably difficult.
