The hierarchical nature of ΛCDM suggests that the Magellanic Clouds must have been surrounded by a number of satellites before their infall into the Milky Way halo. Many of those satellites should still be in close proximity to the Clouds, but some c... Read More about Identifying true satellites of the Magellanic Clouds.

The metal enrichment of passive galaxies in cosmological simulations of galaxy formation (2016)
Journal Article
