Julio F. Navarro Cosmologist

Julio Navarro studies the cosmological implications of the observed properties of galaxies and galaxy clusters. His work on dark matter – the mysterious substance that holds galaxies together – has been highly influential in the crafting of our current paradigm for structure formation in the Universe, where the mass budget is dominated by “cold” dark matter and the universal expansion is driven primarily by “dark energy”. His work uses some of the world’s largest supercomputers and most sophisticated numerical algorithms to recreate the hierarchical formation of galaxies and other structures. These state-of-the-art simulations have highlighted a number of successes and shortcomings of theories of structure formation.
