A visualization of the Glashow event recorded by the IceCube detector. Each colored circle shows an IceCube sensor that was triggered by the event; red circles indicate sensors triggered earlier in time, and green-blue circles indicate sensors triggered later. This event was nicknamed “Hydrangea.” Credit: IceCube Collaboration The South Pole […]

The Russian RATAN-600 telescope helps to understand the origin of cosmic neutrinos. Credit: Daria Sokol/MIPT Press Office Russian researchers trace high-energy neutrino origins to black holes in far-off quasars. Russian astrophysicists have come close to solving the mystery of where high-energy neutrinos come from in space. The team compared the […]
