The IceCube Neutrino Observatory and Nobel Prize in Physics 2026

This year the Nobel Prize goes to Francis Halzen “for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin”. The Observatory uses White Rabbit.

The IceCube Neutrino Observatory (IceCube) is a research facility at the South Pole in Antarctica, maintained and operated by the Wisconsin IceCube Particle Astrophysics Center and scientific analysis performed around the world by members of the international IceCube Collaboration.

In IceCube, a White Rabbit timing system has been deployed in the field since early 2018 as part of the prototype IceTop surface array enhancement, using modified hardware designed for low-temperature operation. The same hardware will be used in the IceCube Upgrade.

IceCube-Gen2, the next generation extension of the IceCube, offers a unique scientific potential for cosmic-ray physics at PeV to EeV energies complementing the main science case of neutrino astronomy. It will use a White Rabbit timing and communication system.
