Title: Gravitational self-force in black hole spacetimes: applications to the two-body problem and a review of recent results

Abstract: The complete, analytical reconstruction of the metric associated with black hole perturbations is the goal of the gravitational self-force (GSF) program. Starting from 2013, the first GSF analytical results have been available, in Post-Newtonian sense,  in the case in which  the perturbing source is a test particle (even with a spinning structure) moving on an equatorial bound orbit around the Schwarzschild or Kerr black hole. After revisiting the main steps of the GSF machinery we will review the status of the art and the main difficulties for future works. Conversion of GSF results in other formalisms like the effective one-body formalism will be shortly considered too.
