The IceCube Neutrino Observatory, the Antarctic neutrino detector that identified the first likely source of high-energy neutrinos and cosmic rays, is getting an upgrade. Seven strings of optical modules will be inserted at the bottom center of the 86 existing strings, adding more than 700 new,…

Neutrinos are exceptionally light particles whose mass requires an update to our theory of particle physics. A new idea to explain their properties has now been published by a team of physicists of the SFB1258 around Alejandro Ibarra, professor for theoretical elementary particle physics at the…

The most comprehensive analysis of neutrinos from core processes inside the Sun has been published by the researchers of the Borexino experiment. For the first time, the scientists have presented a complete assessment of the Sun’s full neutrino spectrum. In a further novelty, they detected neutrinos…

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence…

The neutrino is the lightest and most mysterious of all elementary particles. It is hoped that a better understanding of its properties will provide answers to many unresolved questions relating to the origin of the universe. In order to study these elusive particles in an efficient way, Raimund…

How heavy are neutrinos? The Karlsruhe tritium neutrino experiment KATRIN was designed to answer this important question of modern particle physics and cosmology. It was started after 15 years of construction at the Karlsruhe Institute of Technology (KIT) on 11 June 2018. The SFB1258 is involved in…

Physicists from the Collaborative Research Center 1258 (SFB1258) at the Technical University of Munich develop a new method to determine the velocity distribution of dark matter (DM) particles in our solar system by making use of measurement constraints from different experiments. In this way, the…

Stefan Schönert is awarded an Advanced Grant by the European Research Council to prepare for a new experiment to tackle one of the unresolved puzzles of physics: Why is there so much more matter in our universe than antimatter?

One of the fundamental questions in particle physics is still unanswered: Are neutrinos their own antiparticles? The search for an answer leads to an extremely rare nuclear decay process, the neutrinoless double-beta decay (0nbb). While paving the way for a new ton-scale experiment, the GERDA…

For the first time ever, scientists have measured the electromagnetic and gravitational signals generated by the collision of two neutron stars. In a special research project led by the Technical University of Munich (TUM), physicists with the Collaborative Research Center 1258 "Neutrinos and Dark…
