Large-Scale Structures

Cosmic structures on the largest scales consist primarily of massive galaxy clusters (more than a billion times the mass of the Sun) and giant cosmic voids hundreds of light-years across. The statistics of their number counts, size and shape hold vital cosmological information that can help us understand physics on the largest physical scales.

Our research at the E.A. Milne Centre for Astrophysics focuses on cosmology not only from galaxy clusters and voids, but also diffuse gases in the early Universe – the “Intergalactic Medium”. Understanding the distribution and physical properties of the Intergalactic Medium is a challenge which will be tackled with the upcoming Square Kilometre Array (SKA) radio telescopes, which the UK is a major partner.
