Description
Starting from an asymptotically flat spacetime, we slice it according to Hyperboloidal slices, contraty to the usual Cauchy slices. These allow one to reach Future Null Infinity in a smooth way, which serves as a good approximation to the position of an observer on Earth with respect to sources of gravitational radiation. Until now, the work has managed to simulate a complex scalar field, i.e., a pair particle-anti-particle, which serves as the source term for Maxwell's equations in their covariant form. Convergence has been tested and future plans to add a black hole with charge are discussed.
