摘要：

Gravitational-wave astronomy offers not only new vistas into the realm of astrophysics, but it also opens an avenue for probing, for the first time, general relativity in its strong-field, nonlinear, and dynamical regime, where the theory's predictions manifest themselves in their full glory. We present a study of whether the gravitational-wave events detected so far by the LIGO-Virgo scientific collaborations can be used to probe higher-curvature corrections to general relativity. In particular, we focus on two examples: Einstein-dilaton-Gauss-Bonnet and dynamical Chern-Simons gravity. We find that the two events with a low-mass m approximate to 7 M-circle dot BH (GW151226 and GW170608) place stringent constraints on Einstein-dilatonGauss-Bonnet gravity, alpha(1/2)(EDGB) less than or similar to 5.6 km, whereas dynamical Chern-Simons gravity remains unconstrained by the gravitational-wave observations analyzed.
