Just like many businesses, galaxies grow through mergers and acquisitions. As galaxies are made up of countless individual stars, simulating these mergers is tremendously challenging, even for the most powerful supercomputers. A international team of researchers have produced a new simulation that shows how colliding galaxies are connected by a “bridge” of material, and spew out enormous tails of dust and debris. New programming and hardware upgrades have made this kind of simulation possible to do.
