A series of articles published in the journals “Monthly Notices of the Royal Astronomical Society” and “The Astrophysical Journal Letters” or on the arXiv website describe various aspects of a study on the consequences of the merger of the Milky Way and a dwarf galaxy nicknamed Sausage. A team of astronomers used data collected by ESA’s Gaia space probe to reconstruct that event from 8-10 billion years ago that profoundly influenced the Milky Way.
