Dark Matter may be hitting the right note in small galaxies

Dark matter may scatter against itself only when it hits the right energy. This is what researchers from the Kavli Institute for the Physics and Mathematics of the Universe (Japan), DESY and the Austrian Academy of Science say in a study published in the recent issue of Physical Review Letters. Their idea can explain why galaxies, from the smallest to the biggest, have the shapes they do, providing a plausible ...

Chill Out, ATLAS

Particle detectors like the huge ATLAS detector at CERN’s Large Hadron Collider have to be cooled all the time. When particles collide with each other and the electronic components and sensors of the detectors are working flat out, they generate a lot of heat, which poses a threat to the efficiency of those components and can in the worst case result in overheating. At DESY, a new carbon dioxide cooling has now ...

Solving five big questions in particle physics in a SMASH

The extremely successful standard model of particle physics has an unfortunate limitation: the current version is only able to explain about 15 percent of the matter found in the universe. Although it describes and categorises all the known fundamental particles and interactions, it does so only for the type of matter we are familiar with. However, astrophysical observations suggest that the mysterious dark matter ...
