My latest paper (below) explores these extreme regions of the black-hole scattering parameter space using simulations generated using the Spectral Einstein Code (SpEC). https://arxiv.org/abs/2511.1019616 Nov 2025 11:30 +0000at://did:plc:2ogen6j5b52peuzjkdojz3d3/app.bsky.feed.post/3m5qmbhuyxk2nhttps://bsky.app/profile/hyperbolly.bsky.social/post/3lu3khk3ucs2eWhat happens when high-velocity black holes hurtle past each other in a close encounter, deflecting through spacetime but never merging? My latest paper (below) presents the first simulations of black hole scattering generated using the Spectral Einstein Code (SpEC).

Below is a plot I made for the Einstein Toolkit Blue Book (arXiv:2503.12263) showing the waveforms SXS:BBH:3999 (scatter) and SXS:BBH:4000 (capture).

The initially unbound system loses enough energy at closest approach to become bound leading to a merger. It’s one of the coolest looking simulations I’ve done!
