Bootstrapping the relativistic two-body problem

Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1

We describe the formalism to compute gravitational-wave observables for compact binaries via the effective field theory framework in combination with modern tools from collider phy…

Radiation Reaction and Gravitational Waves at Fourth Post-Minkowskian Order

Christoph Dlapa, Gregor Kälin, Zhengwen Liu +2

We obtain the total impulse in the scattering of non-spinning binaries in general relativity at fourth Post-Minkowskian order, i.e. , including linear, nonlinear, an…

Radiation-Reaction in the Effective Field Theory Approach to Post-Minkowskian Dynamics

Gregor Kälin, Jakob Neef, Rafael A. Porto

We extend the Post-Minkowskian (PM) effective field theory (EFT) approach to incorporate conservative and dissipative radiation-reaction effects in a unified framework. This is ach…

Gravitational radiation from inspiralling compact objects: Spin effects to fourth Post-Newtonian order

Gihyuk Cho, Rafael A. Porto, Zixin Yang

The linear- and quadratic-in-spin contributions to the binding potential and gravitational-wave flux from binary systems are derived to next-to-next-to-leading order in the Post-Ne…

Conservative Dynamics of Binary Systems at Fourth Post-Minkowskian Order in the Large-eccentricity Expansion

Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1

We compute the conservative dynamics of non-spinning binaries at fourth Post-Minkowskian order in the large-eccentricity limit, including both potential and radiation-reaction tail…

From Boundary Data to Bound States III: Radiative Effects

Gihyuk Cho, Gregor Kälin, Rafael A. Porto

We extend the "boundary-to-bound" (B2B) correspondence to incorporate radiative as well as conservative radiation-reaction effects. We start by deriving a map between the total cha…
