Recent years have seen a renewed interest in analytical treatments of the two body problem in gravity. This is mainly due to the recent detections of gravitational waves by LIGO and VIRGO from binary coalescences. The inspiral phase, the initial phase of the coalescence event where the typical velocities of the binary system are small and the constituents are largely separated, is subject to an analytic Post-Newtonian perturbative treatment. Lately, many tools originating from particle physics and QFT have been utilized for the analytic solution of the problem such as EFT methods and modern methods for Scattering Amplitudes. In this seminar, we will review some of the recent advances of this newborn subfield and focus on specific contributions of the speaker.
