Abstract:
After the constraint on the speed of gravitational waves (GW) from 
GW170817/GRB170817A event, a large class of modified gravity theories 
are still viable, which changes the amplitude damping of GW propagation.
However, testing numerous theories one by one would be challenging. I 
will introduce a generalized framework, and our prescription to test the 
gravity theories in a model-independent way. As an application, I will 
show the model parameter distributions in the viable generalized 
scalar-tensor theories, the correlations of the parameters, and the 
possibility for testing the models in the future observations, 
especially GW, screening mechanism and gravitational lensing.
