Gravity Seminars

Continuing the success of gravitational wave observations demands considerable improvements of their theoretical predictions in the next decade, in order to keep their accuracy on par with upgrades of the detectors. This urges innovations on the methods by which gravitational waves from compact binaries are calculated. In this talk, we focus on approaches to analytic, perturbative predictions for relativistic binaries inspired by high-energy physics. In this area, effective field theories are highly useful and scattering amplitudes (the primary observable) can be calculated very efficiently using novel tools. These methods can indeed be applied the classical binaries and their gravitational waves. We give a basic introduction to the ideas of these approaches and recent progress.
