Do Dwarf Galaxies Merge In The Milky Way's Halo?
By Evan Gough (https://ift.tt/nfhTB5X)

This VISTA image shows the Large Magellanic Cloud, which is probably the most well-known dwarf galaxy. It's one of at least 50 dwarf galaxies that are satellites of the Milky Way. Scientists think that dwarf galaxies in galactic haloes merge with one another, but clear evidence is hard to find. New research may have found the best evidence yet.

Our current understanding of the Cosmos shows that structures emerge hierarchically. First there are dark matter densities, then dwarf galaxies. Those dwarfs then merge to form more massive galaxies, which merge together into even larger galaxies. Evidence of dwarf galaxy mergers is difficult to obtain, but new research found some in the Milky Way's halo.
