Aquarius-A-L1
The dark matter distribution of a Milky Way mass halo in a Lambda-cold dark matter (LCDM) cosmological simulation. This is the highest resolution simulation of a MW-mass dark matter halo ever performed, called Aquarius-A-L1. The MW halo (in the centre) is surrounded by myriad substructures, a key prediction of the "cold dark matter” model. Some of these subhalos host a satellite galaxy within them that could be observable.
