The Cannibal Next Door

SIfA Professor Geraint Lewis and his international team,  including with SIfA PhD students Zhen Wen, have unravelled the cannibalistic past of the Andromeda galaxy. This study, published in Nature, analysed globular cluster data from the Pan-Andromeda Archaeological Survey (PAndAS) to reconstruct the times when Andromeda devoured small galaxies to grow its…
