Which clumps of interstellar gas will collapse under gravity to form stars and which clumps will not? This is related to a key problem in turbulence: to understand the distribution of densities produced. Using simulations and analytic work, researchers have been able to both track and model the evolution of densities under...

New ideas for the origin of the ‘cosmic hum’ have been further developed in a couple of recent studies by Excellence Cluster Quantum Universe researchers from DESY, along with collaborators from Heidelberg, Mainz and Oslo. The cosmic hum of gravitational waves was recently observed by pulsar timing arrays yet its origin is...

Daring to try something new, facilitating change - these are topics that come up again and again in the mentoring process. This year, the kick-off of the dynaMENT program at the beginning of October, at which the previous participants were given a ceremonial farewell and new participants were welcomed, also came up with...

For the fifth time, the Cluster of Excellence Quantum Universe invites applications and nominations for its Beate Naroska Senior and Junior Guest Professorships. Applications and nominations are welcome until 30 November 2024.

A group of scientists from the University of Hamburg’s cluster of excellence Quantum Universe and DESY in collaboration with the University of Rochester (USA) observed an unexpected excess in the production of pairs of top quarks and their antiquarks with the CMS detector at CERN’s particle accelerator Large Hadron...

Next spring, particle physicists Eckhard Elsen and Robert Klanner will be awarded the W.K.H. Panofsky Prize in Experimental Particle Physics by the American Physical Society (APS) for their pioneering work at DESY's largest particle accelerator HERA. Both scientists were professors at the University of Hamburg and did...

The 2024 Nobel Prize in Physics has been awarded to John J. Hopkins (Princeton University, USA) and Geoffrey E. Hinton (University of Toronto, Canada) for groundbreaking research that led to the invention of so-called artificial neural networks. Gregor Kasieczka, professor for Machine Learning in Particle Physics at the...

The Clusters of Excellence at the University of Hamburg have joined forces to provide a more extensive webinar offer on mental health. Together with Academic Mental Health & Well-being Consultant Desiree Dickerson, “CUI: Advanced Imaging of Matter”, "Climate, Climatic Change, and Society”, “Quantum Universe” and...

For the first time, quantum entanglement has been observed at energies as high as 13 TeV. This remarkable result stems from top quark measurements by the ATLAS and CMS experiments at CERN. Alexander Grohsjean, a key researcher in the Excellence Cluster Quantum Universe, currently leads the CMS TOP Physics Analysis Group...
