The 2D cross sections of the density and temperature of the binary neutron star merger simulation just before the merger at 7.06 ms, just after the merger at 7.86 ms, and the final simulation time at 18.96 ms. The cross sections are in the xy-plane at z = 0 for the simulation with 3 million particles. We show the density in the top panels and the temperature (capped at 20 MeV for visibility) in the bottom panels.
