Title: Tidal effects in gravitational scattering of massive bodies

Abstract:

Merging neutron stars are a source of detected gravitational waves on earth. This gives rise to an interest in the description of tidal effects in the scattering of two massive bodies of finite size. This thesis extends a WQFT in Post-Minkowskian expansion describing bodies as point masses to quadrupole tidal effects. We use this to provide a correction in LO to the wave form and look at its impact on radiative effects on the deflection. Furthermore we provide a correction to conservative deflection and Eikonal up to NLO.
