Parameterized tests of general relativity with gravitational wave generation and propagation

Abstract

Any modification on gravity would affect not only gravitational wave (GW) generation but also GW propagation. Therefore, tests of general relativity (GR) with only GW generation or GW propagation will lead to an overestimate for deviations. Here we try to use one set of parameters to parameterize the modifications on both GW generation and GW propagation and then test GR with GW150914. In our simplest case, we find that graviton mass $\mu <6.3\times 10^{-23}eV/{\mathrm{c}}^2$ at $90\%$ C.L. and there are no deviations from GR at $90\%$ C.L..
