A sharper view of the Milky Way with Gaia and machine learning

A group of scientists led by the Leibniz Institute for Astrophysics Potsdam (AIP) and the Institute of Cosmos Sciences at the University of Barcelona (ICCUB) have used a novel machine learning model to process data for 217 million stars observed by the Gaia mission in an extremely efficient way. The results were published in the journal Astronomy & Astrophysics.

Research Area I: Cosmic Magnetic Fields

Cosmic events are determined by two natural forces: gravity and magnetic fields. The magnetic field research at the AIP is mainly focused on magnetohydrodynamic (MHD) simulations, the magnetically induced activities on the Sun and the stars, solar coronaphysics as well as space weather in our solar system and on planets around other stars.

New map of the universe shows mega structures

An international research team led by the Leibniz Institute for Astrophysics Potsdam (AIP) has developed a new method of imaging the universe and created a fascinating map of the cosmos based on analysing the motions of 56,000 galaxies. The work shows impressive cosmic structures and maps the large-scale interconnectedness of galaxy superclusters in our universe.
