Research Plan at GCOE

The two-body problem is one of fundamental issues in physics. In Newtonian theory of gravity, it is known that the problem can be reduced easily to one-body problem and solved exactly. On the other hand, in general relativity, the problem is difficult to solve exactly because of the nonlinearity of the theory and the back-reaction due to the gravitational radiation. In my research plan, I am tackling the two-body problem in general relativity with black hole perturbation theory. The study of this problem is not only a theoretical interest, but also plays an important role in the accurate prediction of the gravitational waveforms, which is required for the direct observation of gravitational waves.


I will give the project my best shot.
