An International team led by researchers from the Institute of Astronomy at the University of Tokyo and including scientists from the CEA, the CNRS, the Université Paris Diderot and Sorbonne Paris Cité have used the combined power of multiple astronomical observatories around the world and in space to discover 39 previously unknown ancient massive galaxies. This is the first multiple discovery of its kind and the finding defies current models of the universe. These galaxies are also closely linked with supermassive black holes and the distribution of dark matter. The research is detailed in Nature.
