Extragalactic Archaeology: A New Method To Understand Galaxy Growth and Evolution

Galactic archaeology uses chemical fingerprints in the Milky Way to trace its formation and evolution. Now a team of researchers led by the Center for Astrophysics | Harvard and Smithsonian have employed it for the first time in a distant galaxy. This is the first example of extragalactic archaeology, and it relies on help from the powerful Illustris TNG simulations.
