Reconstructing the mass accretion histories of nearby Red Nuggets with their globular cluster systems

It is generally recognized that massive galaxies form through a combination of in-situ collapse and ex-situ accretion. The in-situ component forms early, where gas collapse and compaction leads to the formation of massive compact systems (blue and red "nuggets") seen at z>1. The subsequent accretion of satellites brings in ex-situ... Show more
