The CosmicDawn ERC Project which maintained this site is now completed! The blog will no longer be updated but is maintained as an archive. You can find many of us over at the UCL Cosmoparticle Initiative.

Welcome to Early Universe @UCL, the homepage for research in early universe cosmology at University College London.

The early universe is a “laboratory” for testing physics at very high energies, up to a trillion times greater than the energies reached by the Large Hadron Collider. The origin of structure in the universe is deeply tied to this extreme physics, which is imprinted in the primordial ripples seen in the cosmic microwave background (the leftover heat of the Big Bang), and the large scale structure of the universe traced by galaxies.

We are based at the UCL Department of Physics and Astronomy, in the Astrophysics Group, and at UCL’s Mullard Space Science Laboratory. On these pages, you can read about our efforts to uncover the secrets of the Big Bang!
