Magnetic Fields in Very Light Extragalactic Jets

We simulate the propagation of very light astrophysical jet with density contrast between 10(-1) and 10(-4) including magnetic fields into the intracluster medium on the galaxy cluster scale, using the magnetohydrodynamic code NIR-VANA on the NEC SX-6 and SX-8. the code runs very efficiently and enables us to perform simulation in both axisymmetry as well as full 3D, using both shared-memory and MPI parallelization. Simulations further supported a stabilization of the contact surface by magnetic fields, as seen in low-frequency radio observations. Efficient storage methods for high time resolution runs as well as visualization methods were implemented and allow in-depth analysis of velocity and magnetic fields.
