An international team, including researchers from the University of Hamburg Observatory, has discovered 31 of the oldest quasars ever found using the European Space Agency’s Euclid space telescope. Two of these massive galactic nuclei now break the record for the earliest quasars ever observed in cosmic history and offer...

Between simple periodic motion and chaos, nonlinear systems can display complex rhythms that never exactly repeat. In a new theoretical study, selected as an Editors’ Suggestion in Physical Review A, researchers from the University of Hamburg and the University of Konstanz show how such quasiperiodic motion survives in open...

At CERN, millions of particle collisions occur every second—far too many to store them all. A clever filtering system therefore decides in real time which data are worth keeping. Researchers from the University of Hamburg in the Cluster of Excellence Quantum Universe have now integrated artificial intelligence directly into...
