The rapid formation of a large rotating disk galaxy three billion years after the Big Bang

Abstract:

Observations and theoretical simulations have established a framework for galaxy formation and evolution in the young Universe. Galaxies formed as baryonic gas cooled at the centres of collapsing dark-matter haloes; mergers of haloes and galaxies then led to the hierarchical build-up of galaxy mass. It remains unclear, however, over what timescales galaxies were assembled and when and how bulges and disks - the primary components of present-day galaxies - were formed. It is also puzzling that...
