Researchers from the Double Chooz collaboration have measured antineutrino emission from spent nuclear fuel for the first time. This discovery opens new perspectives for reactor monitoring, nuclear safety, and safeguards.
Astronomers have detected a new gamma-ray source near Westerlund 1, a young massive star cluster in the Milky Way. The source is connected to a 'nascent outflow' of particles driven by the cluster's collective wind, creating a cavity in the interstellar medium.
The KATRIN collaboration presents the most precise direct search for sterile neutrinos through measurements of tritium β-decay. No sign of a sterile neutrino was found, excluding a large region of parameter space suggested by earlier anomalies. The result relies on distinct detection methods and complements oscillation experiments.
Researchers from two Max Planck Institutes directly observe the strong reshaping of C60 molecules by laser fields using x-ray camera. At low intensities, the molecule expands before fragmentation sets in, while at high intensities, fast expansion and removal of outer valence electrons occur.
Researchers at Max Planck Institute for Nuclear Physics have successfully detected antineutrinos from a nuclear reactor using the CONUS+ experiment. The detection uses Coherent Elastic Neutrino-Nucleus Scattering (CEvNS), allowing for improved sensitivity to new physics beyond the Standard Model.
Researchers at Max-Planck-Institut für Kernphysik recreated a reaction under conditions similar to those in the early universe for the first time. They found that the rate of this reaction remains almost constant with decreasing temperature, contradicting previous predictions.
The study confirms QED theory by measuring the g-factor of lithium-like tin with high precision. The experimental value agrees well with the theoretical prediction within the uncertainty of the calculation.
Prof. Marrodán Undagoitia joins the Dark Matter group at UvA with expertise in astroparticle physics, XENON experiments, and light sensor development. Her appointment strengthens the group's capabilities for ultra-sensitive detectors.
Physicists at Max-Planck-Institut fur Kernphysik measured the g factor of highly charged boron-like tin ions with a precision level of 0.5 parts per billion. The result demonstrates potential for competitive determination of fine structure constant α, governing electromagnetic forces throughout the universe.
Scientists have discovered that even low-mass microquasars can accelerate particles to high energies, producing gamma-ray signals. This finding challenges the long-held belief that only high-mass systems are capable of particle acceleration.
Researchers have made groundbreaking measurements of the electron capture of the artificial isotope holmium-163, which allows them to determine a Q value for the decay process. This enabled them to measure the neutrino mass with unprecedented precision using a super-sensitive scale and detector.
The H.E.S.S. Observatory detected gamma-ray emission from the outer jets of SS 433, revealing a shift in energy-dependent morphology. This suggests strong shock acceleration, where high-energy particles collide with photons, producing x-ray radiation and explaining the X-ray reappearance of the jets.
