Figure 17.

mpeg-Movie (558 KB) Still from a movie showing An animation of a headon collision simulation of two 1.4 M_⊙ neutron stars obtained with a relativistic code [137, 261]. The movie shows the evolution of the density and internal energy. The formation of the black hole in prompt timescales is demonstrated by the sudden appearance of the apparent horizon at t = 0.16 ms (t = 63.194 in code units), which is indicated by violet dotted circles representing the trapped photons. See [245] for download options of higher-quality versions of this movie. (For video see appendix)
