SEMINAR: Gravitational Wave and testing of gravity

Gravitational waves (GWs) provide the excellent opportunity to test General Relativity in strong fields. In this talk, by comparing General Relativity and its alternative, the general screened modified gravity, we introduce the testing of gravity in solar system with PPN framework, in binary pulsars with PPK framework, and in GW bursts. In the last case, we introduce the model-dependent (waveforms of GWs in various alternative theories of gravity) and model-independent comparisons (by PPE framework, GW polarization, GW speed, time-dependence of G, parity symmetry etc.).
