Renormalized Dynamical Friction in Black-Hole Spacetimes

We derive the renormalized local equation of motion for the gravitational self-force on a compact object moving through matter in a black-hole spacetime. We integrate out the environment and metric perturbations on a Schwinger--Keldysh contour, obtaining a causal effective action given by a sum of curved-spacetime Feyn...
