SXS, Simulating eXtreme Spacetimes, and the black hole perturbation toolkit both have web presences, you could start there. There is also an academic literature on matching the waveforms in both regimes. These are checked against results from multimessenger astronomy. &gt; I&#x27;d really love to see what shape two Schwarzschild blackholes (and by that I mean their event horizons because, I don&#x27;t believe anything beyond…</p><p><a href="https://hackerpaper.kaipfister.de/p/1606.00436/">Paper and discussion history</a>.
