Last Wednesday, a gravitational wave detection gave astronomers quite the surprise. As researchers were going about their work at the Laser Interferometer Gravitational-Wave Observatory (LIGO), a pair of gravitational waves rolled in just minutes apart.   The first, labelled S190828j, was picked up by all three of LIGO’s gravitational wave detectors at 06:34 am, coordinated universal time.

The Universe is vast beyond imagination, containing billions upon billions of galaxies. We have a pretty good handle on a lot of galactic dynamics, but how these colossal objects form, grow, and change is still something we’re struggling to understand.   Enter the UniverseMachine: simulation software run on a powerful supercomputer, able to grow millions
