|Binary neutron stars mergers are not only important sources
of gravitational waves, but they are also thought to be at
the origin of very important astrophysical phenomena, such
as short gamma-ray bursts. In order to describe the
dynamics of these events one needs to solve the full set
of general relativistic hydrodynamics and magnetohydrodynamics
(GRMHD) equations through the use of parallel numerical codes.
After an overview on the status of numerical relativity at
AEI, I will present the new Whisky(MHD) code developed to
solve the equations of GRMHD on dynamical spacetimes in
three spatial dimensions and with adaptive mesh refinement
techniques. I will then report on some recent achievements
obtained using this code in simulating binary neutron
stars mergers with and without magnetic fields.
