Recently, in correspondence with the 10th birthday of LOFAR, a core group of researchers including MPA scientists published the most stringent upper limits on the reionization signal from the early Universe. These observations are able to exclude some reionization models and constrain the thermal and ionization state of the intergalactic medium when the Universe was still in its infancy. more

During its general meeting, the Max Planck Society announced that former MPA PhD student Jens Stücker receives one of the Otto Hahn Medals this year. The prize is awarded for numerical investigations of the dark matter phase-space structure in the smallest halos, thereby allowing to better distinguish between Warm and Cold Dark Matter. more

Extracting cosmological information from galaxy surveys is a difficult task – one to which MPA researchers are now one step closer. Using a theoretical framework known as effective field theory combined with a novel statistical approach, they were able to correctly recover the input cosmology based on a catalog of simplified simulated galaxies. more

On 6 May 2020, the Gruber Foundation announced that Volker Springel, managing director at the Max Planck Institute for Astrophysics, receives the 2020 Gruber Cosmology Prize along with Lars Hernquist, Center for Astrophysics | Harvard & Smithsonian, for their defining contributions to cosmological simulations. This method tests existing theories of, and inspires new investigations into the formation of structures at every scale from stars to galaxies to the universe itself. The award recognizes their transformative work on structure formation in the universe, and development of numerical algorithms and community codes further used by many other researchers to significantly advance the field. more

About 10 billion years ago, a galaxy smashed into our cosmic home, the Milky Way, in a violent “merger” event that changed the way the Galaxy looks. Researchers from MPA together with international collaborators from the UK, Chile and Italy, have managed to piece together the impact of this event using the largest and most sophisticated simulations of the Milky Way to date. In particular, they found that the damage inflicted on the Galaxy in its youth is commensurate with a satellite that weights about a billion Suns. more

On 27 April 2020, the US National Academy of Sciences announced that MPA managing director Volker Springel is among the 26 newly elected international members in recognition of his distinguished and continuing achievements in original research. Membership is a widely accepted mark of excellence in science, especially as the "bar" for electing Foreign Associates is supposed to be quite high, particularly for well-represented countries such as Germany. more
