Post-Newtonian and Post-Minkowskian Corrections for Binary Gravitating Systems: Post-Newtonian and post-Minkowskian corrections for binary gravitating systems
- Johannes Bluemlein
- Peter Marquard
Description
Recent developments on analytic results in the field of the post-Newtonian and post-Minkowskian corrections for binary gravitating systems without spin are reviewed. They are of importance in the further refined understanding of gravitational wave signals in the inspiraling phase.

Special attention will be devoted to recent developments in the PN-PM structure of scattering angle of hyperboliclike encounters. -

Theoretical and numerical works on the two-body problem in general relativity (GR) play a very important role when detecting and interpreting the gravitational wave signals. In this talk, we review the present state-of-the-art on traditional post-Newtonian (PN) methods in GR, applied to the gravitational wave and phase evolotion of inspiralling compact binaries. In particular, we emphasize...

The status of the EFT approach to the compact binary problem will be assessed, with a discussion of recent progress in the study of both conservative and radiative dynamics, and a glimpse on possible future developments.

The quest of the perturbative post-Minkowskian study of the gravitational two body problem

has recently seen advances upon employing perturbative quantum field theory techniques. I report on a
novel approach based on a worldline quantum field theory that provides an efficient way to
study the classical scattering of two massive objects (BHs, neutron stars or stars) in GR. We are able to... -

Future gravitational wave detectors will map out and characterize every binary merger in the history of the universe. The possibilities for new and unexpected scientific discoveries from this wealth of data is staggering, but hinges crucially on complementary advances in our theoretical understanding of the nature of gravitational wave sources. However, the path from Einstein’s equation to...

potential corrections to the binary black hole system, also
including the tail terms, except the purely rational terms of
O(\nu^2). Comparisons are made with the literature. The
contributions of O(\pi^2 \nu^2) are calculated for the first
time. We provide the Hamiltonian for harmonic...
