3-D GRMHD Simulation (IMAGE) U.S. National Science Foundation Caption This is a volume rendering of the entropy in a full 3-D GRMHD simulation of a differentially rotating and highly magnetized progenitor to a supernova. Red colors indicate high entropy (hot) material while blue represents low entropy (cold) material. Strongly magnetized material is continously launched from the surface of the proto-neutron star in the center but gets severly distorted such that, instead of a clean jet observed in the ultrastrong magnetic field case, two giant polar lobes are formed. The box size for the visualization is 2000km cubed. GRMHD refers to a general relativistic magentohydronamic simulation.
