Testing f(R) gravity using gravitational-wave signals from binary mergers

Abstract

Recently, several studies have investigated the validity of General Relativity predictions. Gravitational waves provide an ideal probe for testing the theory in the strong-field regime. In this work, we consider a class of modified-grevity theories, specifically f(R), and scrutinize their predictions for the gravitational-wave emission from the coalescence of two astrophysical compact objects. We also assess the impact of next-generation gravitational-wave detectors on the ability of test these estensions of General Relativity.
