报告摘要: Einstein’s general relativity (GR) has passed various tests for more than a century with flying colors. However, there remain open questions related to the mysterious gravitational force, both from theory and observation. Thus it is still highly motivated to search for possible deviations from GR. In principle, gravitation can reduce to GR in the weak-field regime, while still manifesting a large deviation in the strong- field regime, as, for example, predicted by the nonperturbative calculation in the scalar-tensor theories of gravity. Pulsar timing and interferometric gravitational-wave (GW) detectors provide us powerful tools to investigate strong-field gravity with high precision. In this talk, I will review the status of testing strong- field gravity with pulsars and GWs, and the complementarity of the two methods.
