When Dwarfs Dance, Do Galaxies Merge?

When Dwarfs Dance, Do Galaxies Merge?

New research shows how the 'dancing' behaviour of dwarf satellite galaxies can predict mergers between their hosts. A distant pair of galaxies is undergoing the same type of merger that Milky Way/Andromeda will undergo. Can the behaviour of their dwarf satellites tell astronomers what will happen when the MW and Andromeda merge?

Dancing dwarf galaxies predict our Milky Way's future

A UQ survey studied the evolution of twin spiral galaxies about 3 billion years ahead of the Milky Way and Andromeda in merging. It found they could also combine like a dance with the closely located dwarf satellites rotating around them. The researchers say their observations suggest current cosmological simulations need to be overhauled.
