## Numerical simulation of compact objects: black holes and neutron stars

In our universe there are objects with extremely strong gravity, such as black holes

and neutron stars. These objects are under the law of general relativity, which is

valid in very strong gravity. But dynamics of these objects is not fully understood

due to the difficulty of solving Einstein’s equations. In our research group we

solve Einstein’s equations numerically by using computers, follow the dynamics of

black holes and neutron stars and predict possible signals from these objects such

as gravitational waves and electromagnetic ones.
