Gravitational radiation-reaction in arbitrary dimension

Understand

We use effective field theory tools to study non-conservative effects in systems of gravitating objects in general spacetime dimension.

• Using the classical version of the Closed Time Path formalism, we treat both the radiative gravitational field and its dynamical sources within a single action principle.
• New results include the radiation-reaction effective action in arbitrary dimensions to leading and +1PN orders, as well as the generalized Quadrupole formula to order +1PN.
