Why it is important: The distribution of dark matter traces the formation of structure in the universe. Galaxy clusters represent some of the most massive dark matter groupings we can observe, and so determining how their mass is distributed lets us probe how the largest structures formed. Because such massive structures are rare, they can also be a powerful probe of cosmological models.
