The international collaboration, including Fermilab, the National Center for Supercomputing Applications, NOIRLab and others, releases a massive, public collection of astronomical data and calibrated images from six years of surveys. This data release is one of the largest astronomical catalogs issued to date.

The Dark Energy Survey, a global collaboration including the Department of Energy’s Fermi National Accelerator Laboratory, the National Center for Supercomputing Applications, and the National Science Foundation’s NOIRLab, has released DR2, the second data release in…

12/17/2020 More than half of the matter in our Universe has so far eluded our view. Astrophysicists have predicted however where it might be: in so-called filaments, unimaginably long structures made of hot gas that surround and connect galaxies and galaxy clusters. These filaments of hot gas in the computer simulations by Dr. Veronica Biffi and PD Dr. Klaus Dolag at the ORIGINS Cluster of Excellence are strikingly similar in their structure to the 50 million light years long filament which has now been observed for the first time by a team led by the University of Bonn using the…

12/09/2020 The positively charged protons in atomic nuclei should actually repel each other, and yet even heavy nuclei with many protons and neutrons stick together. The so-called strong interaction is responsible for this. ORIGINS member Prof. Laura Fabbietti and her research group at the Technical University of Munich (TUM) have now developed a method to precisely measure the strong interaction utilizing particle collisions in the ALICE experiment at CERN in Geneva.

ORIGINS scientistTil Birnstiel is receiving the 2020 Astrophysical Software Award of the German Astronomical Society for the software he developed for modelling the temporal and spatial evolution of dust in protoplanetary disks. Young stars and the disks around them are built up from interstellar matter which initially contains only very small, at most micrometer-sized, dust particles. Til Birnstiel has written codes describing the mechanisms which lead to the growth of grains over several orders of magnitude in mass and to study how they are distributed and transported in…

09/09/2020 The “IceCube” neutrino observatory deep in the ice of the South Pole has already brought spectacular new insights into cosmic incidents of extremely high energies. In order to investigate the cosmic origins of elementary particles with even higher energies, Prof. Elisa Resconi from the Technical University of Munich (TUM) has now started an international initiative to build a neutrino telescope several cubic kilometers in size in the northeastern Pacific.

07/30/2020 Astrophysicist Sherry H. Suyu will receive the 2021 Lancelot M. Berkeley–New York Community Trust Prize for Meritorious Work in Astronomy. Bestowed annually since 2011 by the American Astronomical Society (AAS) and supported by a grant from the New York Community Trust, the Berkeley prize includes a monetary award and an invitation to give the closing plenary lecture at the AAS winter meeting, the “Super Bowl of Astronomy.” The 237th AAS meeting will be held virtually from 11 to 15 January 2021.

Part of the accelerator ring at KEK

06/26/2020 Tailwind for the search for rare particle decays in the Belle II experiment: The SuperKEKB accelerator ring has now achieved the highest luminosity ever measured. The electron-positron accelerator beats not only its predecessor KEKB but also the Large Hadron Collider (LHC) at CERN. This has just been announced by the Japanese research center KEK, the operator of the accelerator.

The energetic universe as seen with the eROSITA X-ray telescope.

06/19/2020 Over the course of 182 days, the eROSITA X-ray telescope onboard SRG has completed its first full sweep of the sky. This new map of the hot, energetic universe contains more than one million objects, roughly doubling the number of known X-ray sources discovered over the 60-year history of X-ray astronomy. Most of the new sources are active galactic nuclei at cosmological distances, marking the growth of gigantic black holes over cosmic time. Clusters of galaxies in the new map will be used to track the growth of cosmic structures and constrain cosmological parameters.…

[Translate to English:] Open ALICE Experiment

05/27/2020 Since anti-matter could be interpreted as a dark matter annihilation signal, satellite and balloon experiments are currently hunting for dark matter particles near Earth. But anti-matter could also be produced by interactions of high-energy cosmic rays with the interstellar medium. To better understand the production mechanism and the annihilation of anti-matter, the ALICE collaboration has conducted a comprehensive study of the yield of anti-matter resulting from proton-proton collisions and evaluated for the first time the cross section of anti-deuteron at low energies.

05/08/2020 Great honour for ORIGINS scientist Volker Springel: the director at the Max Planck Institute for Astronomy is being awarded the 2020 Gruber Cosmology Prize for his defining contributions to cosmological simulations. Springel shares the $500,000 prize with Lars Hernquist of the Harvard-Smithsonian Center for Astrophysics. The researchers have developed methods to test existing theories about the formation of structures at every scale from stars to galaxies to the universe itself. Springel and Hernquist developed numerical algorithms and community codes which are used by many…
