My recent work is focused on cosmological N-Body simulations. In these simulations, I am trying to simulate our Universe, particularly looking for evidence which would determine whether Einstein`s general relativity is the right theory describing the Universe on large scales. Simulations for gravities other than Einstein’s are computationally even more expensive. We are thus looking for approximations of equations which will reduce the computation time without loss of fidelity. With these fast simulations, we aim to study a large set of modified theories of gravity.
