[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…

04/06/2020 The Belle II experiment started almost exactly one year ago. The renowned journal Physical Review Letters has now published the initial results of the detector. The work deals with a new particle in the context dark matter, which – according to current knowledge – accounts for about 25 percent of the Universe.

01/08/2020 Members of the H0LiCOW team led by ORIGINS Scientist Sherry Suyu at the Max Planck Institute for Astrophysics and the Technical University of Munich used a number of telescopes and a technique that is completely independent of any previous method to measure the universe's expansion rate, a value called the Hubble constant. The researchers' result further strengthens a troubling discrepancy between the expansion rate calculated from measurements of the local universe and the rate as predicted from background radiation in the early universe. The new study adds evidence to the…

10/14/2019 ESO astronomer and ORIGINS Scientist Dr. Leonardo Testi together with Patrick Hennebelle from CEA Paris-Saclay in France, Ralf Klessen from the University of Heidelberg in Germany, and Sergio Molinari from the Istituto Nazionale di Astrofisica in Rome, Italy, were awarded with up to €12.6 million by the European Research Council (ERC) for the project "ECOGAL – Understanding our Galactic ecosystem: From the disk of the Milky Way to the formation sites of stars and planets". This project is one of only 37 synergy grants to be funded by the ERC in 2019 and the only one in the…

09/16/2019 Because of their extremely small mass, neutrinos play a key role in cosmology and particle physics. After evaluation of the first measurement results in the Karlsruhe Tritium Neutrino Experiment (KATRIN), it is now clear: The previously unknown mass of the neutrinos must be less than 1 electron volt. This result is more accurate than previous measurements and raises hopes of discovering new neutrino properties.

Working on the germanium detector array in the clean room at Gran Sasso underground laboratory.

09/05/2019 In the quest to prove that matter can be produced without antimatter, the GERDA experiment at the Gran Sasso Underground Laboratory is looking for signs of neutrinoless double beta decay. The experiment has the greatest sensitivity worldwide for detecting the decay in question. To further improve the chances of success, a follow-up project, LEGEND, uses an even more refined decay experiment.

08/22/2019 It is among the most spectacular events in the universe: a merger of neutron stars. An international team of researchers with strong representation from the Technical University of Munich (TUM) has completed the first laboratory measurements of thermal electromagnetic radiation arising in such collisions. The resulting data enabled them to calculate the prevailing temperature when such stars merge.

04/29/2019 The Helmholtz Excellence Network “Munich Center for Plasma Astrophysics” headed by Professor Frank Jenko from the Max Planck Institute for Plasma Physics (IPP) and Principal Investigator of the Excellence Cluster Origins will commence its work on 1 May. The Center is being funded with around a million euros by the Helmholtz Association of German Research Centres. The main objective will be to contribute to the excellence cluster ORIGINS through studies relating to plasma astrophysics.

03/24/2019 The Belle II detector got off to a successful start in Japan. Since March 25, 2019, the instrument has been measuring the first particle collisions, which are generated in the modernized SuperKEKB accelerator. The new duo produces more than 50 times the number of collisions compared to its predecessor. The huge increase in evaluable data means that there is not a greater chance of finding out why there is an imbalance between matter and anti-matter in the Universe.
