Binary Black Hole Merger GR ray tracer two lensing black holes feed, spiral in, merge and ring down
Cosmos
Galaxies colliding, black holes feeding and merging, dying stars and storm-banded planets. These are our own simulations, inspired by real targets: N-body gravity, hydrodynamics and a general-relativistic ray tracer.
Galaxy collisions N-body + gas 34–40M particles · Antennae, Mice, Milky Way + Andromeda
