Current models of massive galaxy formation suggest that they evolve as part of a slow growth process, gradually increasing in size through mergers with smaller galaxies and the accumulation of clumps ...

A massive, rotating disk galaxy from the early universe has been discovered by an international team of astronomers. Galaxy DLA0817g, dubbed the "Wolfe Disk" after the late astronomer Arthur M. Wolfe, ...
