Gravitational wave observation GW150914 with black hole merger simulation

I couldn’t find anyone that had combined the gravitational wave chirp observed by LIGO with the simulated visualisation of the putative black hole merger by SXS, so I decided to give it a try myself. Consider it to be illustrative, rather than rigorous.

In the first run-through, the LIGO gravitational wave observation from 2015 Sept 14 (audio chirp) is speed and pitch adjusted to match the SXS visualisation. Mergers 2-5 adjust the SXS simulation to match the chirp, alternating between native and pitch-adjusted frequency to cater to human hearing.
