Description
One way of modifying gravity is by adding additional fields to the action. In this talk, I will demonstrate how to compute the effect of such additional fields on a binary's gravitational potential. As will be discussed, the gravitational waveform generated by a compact binary is highly dependent on the potential, and thus such extensions of gravity may be detectable by gravitational waves.
The talk might be modified to focus more on LIGO activities if relevant.
