Summary

[edit]
Description
English: This simulation follows the collision of two spiral galaxies that harbour giant black holes. The collision merges the black holes and stirs up gas in both galaxies. The merged black hole gorges on the feast and lights up, forming an active galactic nucleus called a quasar and creating a "wind" that blows away much of the galaxy's gas.
