A compact object captured by a supermassive black hole, named as extreme-mass-ratioinspiral (EMRI), is one of the most important gravitational wave sources for low-frequencyinterferometers such as LISA, Taiji, and TianQin. EMRIs can be used to accurately map the space-timeof the central massive body. In the present paper, we introduce our recent progress on testing gravitytheory with EMRIs. We demonstrate how to constrain gravitational wave dispersion and measurethe deviation of the central body from the Kerr black hole. By using binary-EMRIs, the gravitationalrecoil and mass loss due to merger will be measured in a higher accuracy compared with the currentLIGO observations. All these potential constrains and measurements will be useful for test of thegravity theory. |
