Jet launching and propagation in BNS ejecta

Following the merger of two neutron stars, an accretion disk forms around the newly formed black hole. The magnetic flux that falls onto the black hole generates through Blandford-Znajek mechanism (Blandford & Znajek 1977) Poynting flux dominated jets along the polar axes. In our simulations the metric is tilted to avoid numerical dissipation on the jet axis.
